Question

A ball is thrown straight up. What are its velocity and acceleration at the highest point?

Answer 1

Dear student,
When a body is thrown upward its velocity keeps on decreasing because of the deceleration due to acceleration due to gravity (g) which pulls the body in downward direction. At the maximum height velocity becomes zero. Therefore, velocity at the top is zero and acceleration is acceleration due to gravity (g).

Hence we conclude that, at the top

1. Velocity = 0

2. Acceleration = g
