A ball is thrown from a point with a speed v0 at an angle of projection θ. From the same point and at the same instant a person starts running with a constant speed v02 to catch the ball. Will the person be able to catch the ball? If yes, what should be the angle of projection
Yes,60∘
Person will catch the ball if its velocity will be equal to horizontal component of velocity of the ball.
v02=v0 cos θ⇒cos θ=12⇒θ=60∘
