Question

A ball is tossed upwards into the air with an initial upwards velocity of 3.0m/s. What is the ball's velocity when it returns to the height from which it was tossed?

Answer 1

• Same as initial velocity.
• Acceleration due to gravity is 9.8m/s^2

Which is constant on the whole way of travel of the ball.

As no change in acceleration there is no change in velocity at end and it remains at 3m/s
