A ball is hit by a batsman at an angle of `37^(@)` as shown in figure. The man standing at `P` should run at what minimum velocity so that he catches the ball before it strikes the ground. Assume that height of man is negligible in compariosn to maximum height of projectile.

A

`3 ms^(-1)`

B

`5 ms^(-1)`

C

`9 ms^(-1)`

D

`12 ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`T = (2u_(y))/(a_(y)) rArr T = (2xx15 xx sin 37^(@))/(10) rArr T = 1.8 sec`
`u_(min) = (dis tan ce)/(time) = (9)/(1.8) = 5m//s`
