A boy throws a ball with a velocity u at an angle `theta` with the horizontal. At the same instant he starts running with uniform velocity to catch the ball before it hits the ground. To achieve this he should run with a velocity of

A

`u cos theta`

B

`u sin theta`

C

`u tan theta`

D

`u sec theta`

Text Solution

Verified by Experts

The correct Answer is:
A
Velocity of boy should be equal to the horizontal component of velocity of ball i.e., `u cos theta`.
