A ball is thrown from a point with a speed `v_0` at an angle of projection `theta`. From the same point and at the same instant, a person starts running with a constant speed `v_0//2` catch the ball, Will the person be able to catch the ball ? If yes, what should be the angle of projection ?

A

Yes, `60^(@)`

B

Yes, `30^(@)`

C

No

D

Yes, `45^(@)`

Text Solution

Verified by Experts

The correct Answer is:
1
Both horizontal direction speed is same
`v_(0) cos theta=v_(0)/2 rArr cos theta=1/2rArr theta=60^(@)`
