Question

A ball is thrown into the air at an angle. What is the acceleration of the ball at the top of the flight in the x-direction?


A ball is thrown into the air at an angle. What is the acceleration of the ball at the top of the flight in the y-direction?

Answer 1

Answer:

$a_x=0m/s^2\\a_y=-9.8m/s^2$

Explanation:

Assuming that air resistance is negligible then there will be no acceleration in the x-direction as there are no unbalanced forces in the x-direction.

In the y-direction there will be only one force acting and that will be gravity, thus the resultant acceleration will be the acceleration due to gravity (or $9.8m/s^2$ down)

((Newton's first law - a body will continue in it's state of rest or unaccelerated motion unless acted on by an unbalanced force; Newton's second law - F=ma))
