A ball is projected horizontally from an inclined plane with a velocity V, as shown in the figure. It will strike the plane after a time

Two particles A and B are projected simultaneously in a vertical plane as shown in figure. They collide at time t in air. Write down two necessary equations for collision to take place.

Two balls are projected vertically upward with same speed 35 m/s in 3s interval. Find height at which both balls collide.

A ball A is projected with speed 20 m//s at an angle of 30^(@) with the horizontal from the ground. Another ball B is released simultaneously from a point on the vertical line along the maximum height of the projectile. Both the balls collide at the maximum height of the first ball. The initial height of ball B is
