A ball is thrown from a point with a speed v 0 at angle of projection θ. From the same point and at the same instant, a person starts running with a constant speed v 0 /2 to catch the ball? If yes, what should be the angle of projection?
Text Solution
Verified by ExpertsThe correct answer is:
A
Man will catch the ball if the horizontal component of velocity becomes equal to the constant speed of man i.e.
v 0 cosθ = 
⇒ cos θ= 
⇒ cos θ = cos 60º
∴ θ = 60º
