A toy plane is flying horizontally at 10 m / s at height 80 m above the ground toward a man on the ground as shown, when plane is 60 m away horizontally from man, a ball is dropped by the plane. Find speed of man (assumed uniform) so that he is able to catch the ball just before it strikes the ground :-
