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 instance a person starts running with a constant speed `V_(0)/sqrt2` to 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:
A
For.the person to able to catch the ball, the horizontal component of velocity of the ball should be same as the speed of the person i. e,
`v_(0)cos theta=(v_(0))/(2) or cos theta=(1)/(2) or theta=60^(@)`
