The boy velocity = horizontal velocity of the ball = u cos θ

Q. A boy throws a ball with a velocity $u$ at an angle $θ$ 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 :-

$u cos θ$ $

u \sin \theta$

$u tan θ$

$u^{2} tan θ$

The boy velocity $=$ horizontal velocity of the ball $= u cos θ$
