a bowling ball collides with a pin and pushes the pin toward the right. which describes the reaction force?

a. the pin pushes the bowling ball toward the right.

b. the pin pushes the bowling ball toward the left.

c. the bowling ball pulls the pin toward the right.

d. the bowling ball pulls the pin toward the left.

B.The pin pushes the bowling ball toward the left.

Explanation:

Remember Newton´s third law of motion:

"For every action, there is an equal and opposite reaction."

This means that if the bowling ball is pushing the pin towards the left, the pin is also pushing the ball in the opposite direction because of the resistance that the pin could present to the bowling ball, since the resistance possible isn´t that great, the bowling ball is not pushed as much as the pin, but there´s still the same reaction against the bowling ball.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
