Question

A tennis player tosses a tennis ball straight up and then catches it after 1.71 s at the same height as the point of release.

(a) Find the initial velocity of the ball.

(b) Find the maximum height it reaches.

Step 1

Given,

Step 2

**(a) Initial velocity of the ball: -**

By the formula of time of flight of projectile path:

Step 3

**(b) Maximum height: -**

By the formula of maximum height of projectile motion:
