If a 70 kg. skater acted upon by an unbalanced force of 161 N [West], what is
its acceleration?

Answers

According to Newtonʼs Second Law of Motion:

F net = m  x  a

or

a = F net / m

Acceleration = net Force/ Mass = 161 / 70 = 2.3 m/s^2  [W]

If a 70 kg skater is acted upon by an unbalanced force of 161 N [West], his acceleration would be 2.30  m/s² towards the west

What is Newton's second law?

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

The mathematical expression for Newton's second law is as follows

F = m*a

where F represents the force applied

m is the mass of the object

a is the acceleration of the object

As given in the problem If a 70 kg. skater acted upon by an unbalanced force of 161 N

F =ma

By substituting the values of the force and the mass as 161 N and 70 kg respectively

161 N = 70×a

a= 2.30 m/s²

Thus, If a 70 kg skater is acted upon by an unbalanced force of 161 N, his acceleration would be 2.30  m/s² towards the west

What is the force of a 13kg ball that has been dropped and has fallen for 1 second?

Answers

Answer:

127.4 newtons

Explanation:

Assuming g = 9.8:

F = ma = 13(9.8) = 127.4 N

The force of a 13 Kilogram ball that has been dropped and has fallen for 1 second, then the force offered by the ball would be 127.53 Newtons.

What is Newton's second law?

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

As given in the problem we have to find the force of a 13-kilogram ball that has been dropped and has fallen for 1 second,

The force of the dropped ball = mass of the ball × acceleration due to gravity

The force of the dropped ball = 13 × 9.81

                                                  = 127.53 Newtons

Thus , the force of a 13kg ball that has been dropped and has fallen for 1 second would be 127.53 Newtons.

Think about the reasons behind the cost of the Birkin bag and explain why it costs $60,000 in your own words. Do you think that this is a good marketing strategy? Why? Can you think of any other products (clothes / elctronics / anything) that use the same strategy? Does it work?

Answers

Answer:

In terms of both price and availability, the Birkin bag is as elusive as it is exclusive. For more than two decades, the bag has been the most sought item in the handbag industry. For such a modest bag, that's a lot of staying power (in looks alone, the design itself takes some 18 hours and is done by a single craftsman).

Of course, it's likely that the bag's rarity is what keeps it at the top of every want list. It is difficult, for example, to stroll into a Hermès store and buy a bag –– even if you could afford to pay the minimum price of $10,000. No, you have to be on an elite list to receive a Birkin.

Explanation:

There are alot more things like the Birkin Bag that use the same marketing skills and it works for alot of companies.

The answer is -7m, but I don’t know how that’s the answer. Can anyone explain?

Answers

Explanation:

At first it is in 14m position but position doesn't matter in displacement, similar case for time taken.

So at first it travels 6m in positive direction.

So displacement= 6m

Then it travels 13 in opposite or negative direction.

So displacement = 6 -13 m = -7 m

( In 1.5s the speed of the jumper increases from zero to 10.5 m/s. Calculate her average acceleration during this time.​

Answers

Answer:

answer 7m/s^2

Explanation:

›»› The Acceleration of jumper = 7 m/s²

Given :

Initial velocity of jumper (u) = 0 m/s

Final velocity of jumper (v) = 10.5 m/s

Time taken by jumper (t) = 1.5 sec

To Find :

Acceleration of jumper (a) = ?

Required Solution :

→ Initial velocity (u) = 0 m/s (because jumper increase from zero)

† From first equation of motion

⇒ v = u + at

⇒ 10.5 = 0 + a × 1.5

⇒ 10.5 = 0 + 1.5a

⇒ 10.5 = 1.5a

⇒ a = 10.5/1.5

⇒ a = 7 m/s²

║Hence, the Acceleration of jumper is 7 m/s².║

\:

Additional Information :

★ First equation of motion :

⪼ v = u + at

Where,

v is the Final velocity in m/s.

u is the Initial velocity in m/s.

a is the Acceleration in m/s².

t is the Time taken in second.

★ Second equation of motion :

⪼ s = ut + ½ at²

Where,

s is the Distance travelled in m.

u is the Initial velocity in m/s.

a is the Acceleration in m/s².

★ Third equation of motion :

⪼ v² = u² + 2as

Where,

v is the Final velocity in m/s.

u is the Initial velocity in m/s.

a is the Acceleration in m/s².

s is the Distance travelled in m.

Henry ran a 100 m race. Use the graph to answer the following:
a. How long did it take for Henry to run 100 m?
b. What is Henry's average speed over the race?

Answers

Using the graph, which describes how Henry ran the 100m race;

a) It takes Henry 20seconds to run 100m

b) Henry's average speed over the race is; 5m/s.

According to the linear graph which describes the distance ran by Henry during the 100m race as a function of time.

a) Since the distance from start ran by Henry is plotted on the vertical axis, and the time is plotted on the horizontal axis;

To determine how long it took Henry to run 100m; The point corresponding to 100m is traced downward from the line of the graph and we find out that;

It takes Henry 20seconds to run 100m

b) Henry's average speed over the race is simply;

The slope of the distance-time graph.

Therefore,

Average speed = (100-0)/(20-0)

Average speed = 100/20

Average speed = 5m/s.

Therefore, Henry's average speed over the race is; 5m/s.

Question 5 (1 point) true or false: Balanced forces acting on an object result in constant velocity True False​

Answers

Answer:

false

Explanation:

By Newton's first law (An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force), neither speed nor direction change. Our force is balanced.

Balance forces could happen when the object is at rest but not all the time. A balance force is when a object is being push in opposite directions, which would cause the object to stay still or move at a constant speed. Which would mean that balance force could take place when a object is moving or when a object is at rest.

As the unicorn slowed down I realized we were going into pitch-black darkness. I tried to make the unicorn turn back but I couldnt. I heard a shrill screaming and I didnt know where it was coming from.Are you still screaming? Someone said behind me. Surprisingly, there was a girl around my age looking straight at me. Um, what? I said confused. You were screaming, she said smiling. And very loudly I might add. Sorry I didnt even realize it. I said embarrassed. I looked forward and saw a huge bush that the unicorn was about to crash into.I was exhilarated to see that the bush opened into a doorway that led to a dazzling golden castle. As the unicorn went through the doorway I saw so many pixies and more unicorns than I could count. As I came closer to the castle I saw that the castle grew a story bigger. I got off the unicorn and walked up the front steps. As I approached the door someone grabbed my hand. This place is like a double rainbow over a shimmering lake. I heard behind me.Hey, are you a fairy or a witch? A girl asked curiously as I turned around. Um, does it matter? I said questioningly. Yeah, if your a witch youre evil and if your a fairy youre nice. She said. But what if a witch is nice and a fairy is mean. That wouldnt make much sense to your logic then, would it? I said trekking back up the stairs.As I went into the building up the stairs I saw an office with a girl at the desk of about 15 years old. Hey, do you know who the headmistress is?
