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

Options

A. Yes , `60^@`
B. Yes , `30^@`
C. No
D. Yes , `45^@`

Answer

A

Explanation

The person will catch the ball if his speed and horizontal speed of the ball are same.
`:. v_0 cos theta=v_0/2 " or " cos theta=1/2= cos 60^@" or " theta =60^@`
