An arrow is shot from a height of 1.5 m toward a cliff of height H. It is shot with a velocity of 30 m/s at an angle of 60° above the horizontal. It lands on the top edge of the cliff 4.0 s later. (a) What is the height of the cliff? (b) What is the maximum height reached by the arrow along its trajectory? (c) What is the arrow's impact speed just before hitting the cliff?

Answers

Answer 1

Known Variables:

Δy = 1.5 m

v0 = 30m/s at 60° above the horizontal.

t = 4.0 s

a. vfy = v0y + at

0 = 30sin(60) + (-9.8)t

-25.98 = -9.8t

t = 2.65.

4-2.65 = 1.35s.

Δy = v0yt + at^2/2

Δy = 25.98(2.65) + (-9.8)(2.65)^2/2

Δy = 34.44 m

1.5 + 34.44 = 35.94 m.

Δy = v0t + at^2/2

Δy = (-9.8)(1.35)^2/2

Δy = -8.93.

35.94 - 8.93 = 27.01 m.

b. vfy = v0y + at

0 = 30sin(60) + (-9.8)t

-25.98 = -9.8t

t = 2.65.

Δy = v0yt + at^2/2

Δy = 25.98(2.65) + (-9.8)(2.65)^2/2

Δy = 34.44 m

1.5 + 34.44 = 35.94 m.

vfy = v0y + at

vfy = (-9.8)(1.35)

vfy = -13.23 m/s.

I might have gone wrong somewhere so please check my answer! Cheers!

Explain one difference between the teachings of Martin Luther and those of another critic of the Catholic Church in the period from 1500-1550.

Answers

Answer:

He believed the Catholic Church got it wrong on salvation

This was (and, for many, remains) the defining difference between Protestants and Catholics. ... Luther believed people were saved by faith alone and that this was the summary of all Christian doctrine, and that the Catholic Church of his day had got this wrong

Luther held that salvation comes via faith alone and that this sums up everything of Christian philosophy; he thought the Catholic Church of his day had it wrong.

What teachings of Martin Luther and Catholic Church?

It is frequently claimed that Catholics, as opposed to Protestants, think that salvation requires both faith and works.

Calvin and Luther had very similar ideas about God. The two are primarily different in their focus rather than in their differences in content.

According to Calvin, God is an omnipotent personal deity who controls everything. He held the same view of God's absolute sovereignty that Luther did.

This was (and, for many people, still is) the key distinction between Protestants and Catholics. Luther held that salvation is by grace through faith alone, and that this sums up all of Christian doctrine.

Therefore, He believed the Catholic Church got it wrong on salvation.

Find examples of figurative language in "Hip Hop Planet." How does McBride
use them to connect to his audience and achieve his purpose?

Answers

The examples of figurative language used in "Hip Hop Planet" are;

- Irony

- Irony- Metaphor

- Irony- Metaphor The way he used them to pass his message across has been explained below.

Hip hop planet was a persuasive essay written by James McBride's. It was mainly focused on the personal interactions he had with the development of Hip Hop culture as well as the changing interpretations of that movement in the whole world.

Some of the figures of speech he used were irony, metaphor and hyperbole.

1) Irony; He made use of this figure of speech when he said; "It is no longer my world. It is his world. And I live in it. I live on a hip hop planet."

This statement was made in order to elucidate his feelings about hip hop culture. In saying this, it made it clear he felt detached from that hip hop culture and the world.

This made the characteristic of the hip hop culture clear because McBride by using this ironical statement had passed across to the audience his genuine emotions and experiences about this hip hop culture.

2) Metaphor; He made use of this figure of speech when he said; "When I was young, I was a knucklehead too."

He made this metaphorical statement in an attempt to compare himself to the fiancée of his daughter in a simple manner. This method has helped to elucidate his feelings about hip hop culture because it clearly makes the audience to know that he has a very strong background understanding that makes him qualified to criticize the acts and people that are associated with the hip hop culture.

Analyze the causes and effects in the rise of a national American identity from 1754 to 1800.

Answers

Answer:

From 1754, with the beginning of the French and Indian War, the population of the then British colonies in America began to acquire a feeling of national unity based on the common characteristics of the colonists, the culture of the colonies and the confrontation to a common enemy such as the French.

With the end of the war in 1763, the colonists understood that they did not need Great Britain to defend themselves from external threats, since the colonies alone had defeated the French. Then, added to this, the imposition by Parliament of a series of unfair taxes caused the colonists to rebel against Great Britain, considering themselves a different nation with its own idiosyncrasies.

This originated the beginning of the Revolutionary War, where the colonies embraced the liberal ideology to form a new nation, the United States of America.

According to the information in the graph, it can be inferred that women in France have greater female empowerment.

What is female empowerment?

Female empowerment is a term to refer to the taking control of different resources and materials by women that allow them to increase the implementation of their political, social and economic capacities, leading social changes that produce changes in the pre-existing order.

What actions do empowered women take?

In general, the empowerment of women is related to their role in society because in the past it was believed that women were not citizens, did not have rights and did not have the opportunity to make decisions. However, since the middle of the 20th century, women have empowered themselves and modified some pre-existing conservative thoughts.

What type of empowerment does the graph show?

Empowerment shows the birth rate. This is an indicator of empowerment because it can be inferred that the most empowered women have low tendencies to have children because they have spent their lives in other activities such as employment, study, leisure, among others.

According to the above, women in France are those who are more empowered because the birth rate is the lowest shown in the table.

What scene in the show friends represents cognitive dissonance

Answers

Professor Gent described three hypotheses to reduce the dissonance we feel when our actions and attitudes do not meet. The first of these is selective exposure, which describes how we try to limit our exposure to warm accepting environments where people have similar beliefs as us. We tend to avoid information and situations that may cause dissonance. The second is post decision, which takes place after we have made a decision that causes strong doubts. We tend to have a need for reassurance. And finally, there is minimal justification. This argues that if we want to spark an attitude change in others, we need to motivate them (Gent, “Cognitive Dissonance Theory”). These can be found in season 4, episode 16, “The One with the Fake Party.” In this episode Phoebe is pregnant with her brother’s triplets and is having bad morning sickness. She is a vegetarian, but the only food that does not make her want to throw up is meat. She is torn between her beliefs as a vegetarian and what her babies want to eat, an example of dissonance. She eats a meat filled sandwich and Joey stops her, telling her it is against her beliefs. Phoebe instantly feels guilty about it and like she has murdered a cow. She needs reassurance, so Joey promises that he will not eat any more meat until the babies are born so that Phoebe can, and no extra cows will die, justifying her meat-eating habits. (270)
