A ball is thrown from a point with a speed 'v^(0)' at an elevation angle of `theta` . From the same point and at the same instant , a person starts running with a constant speed `('v_(0)')/(2) ` to catch the ball . Will the person be able to catch the ball ? If yes, what should be the angle of projection `theta` ?

A

No

B

Yes, ` 30 ^@ `

C

Yes, `60 ^@ `

D

Yes, `45^@`

Text Solution

Verified by Experts

The correct Answer is:
C
Person will catch the ball if its velocity will be equal to horizontal component of velocity of the ball. `v_(0)/2=v_(0) cos theta rArr cos theta=1/2 rArr theta=60^(@)`
