Explanation:

I may be wrong, but I'm almost positive cuz I am also taking physics. ;)

Answer:

Constant acceleration in the positive direction.

Explanation:

Because it is a straight line with a positive slope, we can infer that the rate of acceleration remains constant as the line is linear, and as it states in the question, the slope is positive; therefore, it is moving in a positive direction.

Answer:

answer is number (a) If the car is moving on a straight road....

Explanation:

The distance moved and magnitude of displacement are equal only in the case of motion along a straight line. Because displacement is the shortest path between initial and find path. So, for car moving on straight road, distance moved and magnitude of displacement are equal.

The combination of a particle's mass and velocity produces momentum. Momentum is a vector quantity that has both magnitude and direction. The force exerted on a particle is equated to the time rate of change of momentum by Isaac Newton's second equation of motion.

What is Newton's Law of motion?

First law of Newton : According to Newton's first law of motion, if a body is at rest or moving in a straight path at a constant speed, it will stay in that state or continue to move in that direction unless it is acted upon by an outside force.

Second law of Newton : According to Newton's second rule of motion, a body's rate of momentum change is inversely proportional to the force acting on it, and momentum changes occur in the direction of the net applied force.

Third law of Newton : Newton's third law of motion states that there is always an equal and opposite reaction to every action.

In order to accomplish work and to produce heat and light, energy must be transferred to a body or to a physical system. Energy is the quantitative attribute that does this.

A push or pull that an object experiences as a result of its interactions with its environment is known as a force.

Un avión vuela hacia al norte a una velocidad de 90 m/s, pero un fuerte viento sopla hacia al este a 20 m/s y desvía su rumbo. Realiza los trazos y encuentra el vector resultante.

Answers

La adicion de vectores permite encontrar la repuesta para la velocidad resultante del avión es:

Modulo de la veloicdad  v= 92,2 m/s Dirección de esta veloicdad 12,5º al Norte del Este  

Las magnitudes vectoriales son cantidades tienen modulo y dirección, la velocidad es una de estas magnitudes, por lo tanto deben ser sumada usando álgebra vectorial.

Un sistema de referencia es un sistema desde donde realizar las mediciones, en este caso indican que usemos un sistema de los puntos cardinales.

En el adjunto podemos ver un esquema de los vectores velocidad y su resultante, realicemos el calculo de la resultante por método analíticos

Indican que el valor de la velocidad hacia el Este es vₓ = 20 m/s y la velocidad hacia el Norte es v_y = 90 m/s, por lo tanto, para la magnitud usamos el Teorema de Pitágoras

           [tex]R= \sqrt{v_x^2 + v_y^2}[/tex]

           R = [tex]\sqrt{20^2 + 90^2}[/tex]

          R = 92,2 m/s

Para encontrar la direccion usemos trigonometría

          tan θ = [tex]\frac{v_y}{v_x}[/tex]

          θ = tan⁻¹ [tex]\frac{v_y}{v_x}[/tex]

          θ = tan⁻¹ 20/90

          θ = 12,5º

La dirección se lee 12,5º al Norte del Este

En conclusión usando la suma de vectores  podemos encontrar la repuesta para la velocidad resultante del avión es:

v= 92,2 m/s  con dirección 12,5º al Norte del Este

An astronaut holds a rock 100m above the surface of Planet X. The rock is then thrown upward with a speed of 15m/s, as shown in the figure. The rock reaches the ground 10s after it is thrown. The atmosphere of Planet X has a negligible effect on the rock when it is in free fall. Determine the acceleration due to gravity on Planet X.

Answers

The acceleration due to gravity of the planet X is 1 m/s².

The given parameters;

height above the ground, h = 100 minitial velocity of the rock, u = 15 m/stime of motion of the rock, t = 10 s

The acceleration due to gravity is calculated as follows;

[tex]h = ut - \frac{1}{2} gt^2\\\\100 = 15(10) - (0.5\times 10^2)g\\\\100 = 150 - 50g\\\\50g = 150-100\\\\50g = 50\\\\g = 1 \ m/s^2[/tex]

A quarter is flipped from a height of 1.45 m above the ground. How much time will it take to reach the ground if the person flipping the coin gave it a velocity of 10.32 m/s? Please answer in seconds and to the third decimal place.

Answers

It will take the quarter 0.151 seconds to reach the ground.

Given the following data:

Height = 1.45 metersInitial velocity = 10.32 m/s

We know that acceleration due to gravity (a) for an object is equal to 9.8 meter per seconds square.

To find how much time it will take the quarter to reach the ground, we  would use the second equation of motion.

Mathematically, the second equation of motion is given by the formula;

[tex]S = ut + \frac{1}{2} at^2[/tex]

Where:

S is the height or distance covered. u is the initial velocity. a is the acceleration. t is the time measured in seconds.

Substituting the values into the formula, we have;

[tex]1.45 = 10.32(t) + \frac{1}{2} (9.8)t^2\\\\1.45 = 10.32t + 4.9t^2\\\\4.9t^2 + 10.32t - 1.45 = 0[/tex]

The standard form of a quadratic equation is:

[tex]ax^2 + bx + c = 0[/tex]

a = 4.9, b = 10.32 and c = 1.45

We would solve the above quadratic equation by using the quadratic equation formula;

[tex]x = \frac{-b\; \pm \;\sqrt{b^2 - 4ac}}{2a}[/tex]

Substituting the values, we have;

[tex]t = \frac{-10.32\; \pm \;\sqrt{10.32^2\; - \;4(4.9)(1.45)}}{2(4.9)}\\\\t = \frac{-10.32\; \pm \;\sqrt{106.5024\; - \;28.42}}{9.8}\\\\t = \frac{-10.32\; \pm \;\sqrt{78.0824}}{9.8}\\\\t = \frac{-10.32\; \pm \;8.84}{9.8}\\\\t = \frac{-10.32\; + \;8.84}{9.8}\\\\t = \frac{1.48}{9.8}[/tex]

Time, t = 0.151 seconds.

Therefore, it will take the quarter 0.151 seconds to reach the ground.

Two balls are dropped from rest and allowed to fall. If one ball is allowed to fall for 1 s and the other for 3 s compare the distances they have fallen.

Answers

The second ball traveled a greater distance when compared to the first ball because the second ball spent more time in motion.

The given parameters;

time of fall of the first ball, t = 1 stime of fall of the second ball, t = 3 s

The distance traveled by each ball is calculated using the second equation of motion as shown below.

The distance traveled by the first ball is calculated as follows;

[tex]h = u_0t + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 1^2)\\\\h = 4.9 \ m[/tex]

The distance traveled by the second ball is calculated as follows;

[tex]h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 3^2)\\\\h = 44.1\ m[/tex]

Thus, the second ball traveled a greater distance because it spent more time in motion.

A cheetah has an average velocity of 70 mph. If a cheetah was chasing a water buffalo for 23 miles, how long was the cheetah chasing its prey? (Recall that there are 60 minutes in one hour.)
180 minutes
27 minutes

3 minutes

Answers

Answer:

20 minutes

Explanation:

Create a proportion.

x = time for 23 miles of travel

70 miles/hr = 23 miles/ x

--- Cross Multiply

70x = 23  --- Divide 70 on both sides

x = 0.32857 hrs....

multiply your value of "x" by 60 min/hr in order to convert to minutes

0.32857 hrs * 60min/1hr

hr(s) cancels out

x = 19.7143... ~ 20 mins
