Question

A ball is thrown straight up with a speed of 36.0 m/s. How long does it take to return to its starting point?

Answer 1

A ball is thrown straight up with a speed of 36.0 m/s.

The time taken to reach the top is given by

`v_y=v_o-gt`

Where vy is the vertical height of the ball, v0 is the speed of the ball, g is the gravitational acceleration (9.8 m/s²) and t is the time taken to reach the top.
