Consider the situation as shown in the figure.

Two balls are thrown simultaneously with same speed `10 m//s`, one horizontally and another at angle `60^(@)` in downward direction. After sometime balls cllide in mid-air, find distance `d`.

Two balls of different masses are thrown vertically upwards with the same speed . They pass through the point of projection in their downward motion with the same speed ( Neglect air resistance ).

Two balls of different masses are thrown vertically upwards with the same speed . They pass through the point of projection in their downward motion with the same speed ( Neglect air resistance ).

A ball is dropped from the top of a tower. After 2 s another ball is thrown vertically downwards with a speed of 40 m//s . After how much time and at what distance below the top of tower the balls meet?

Three identical balls are thrown from the top of a building, all with the same initial speed. As shown in figure., the first ball is thrown horizontally, second above horizontal level, and third at an angle below the horizontal. Neglecting air resistance, rank the speeds of the balls at the instant each hits the ground.

A ball of mass m is thrown at an angle of 45^(@) to the horizontal,, from the top of a 65 m high tower AB as shown in Fig. at t = 0 . Another identical ball is thrown with velocity 20 m//s horizontally towards AB from the top of a 30 m high tower CD 1 s after the projection of the first ball. Both the balls move the same vertical plane. If they collide in mid-air, the height from the ground where the two balls will collide is
