Two identiacal masses are as shown in figure. One is thrown upwards with velocity 20 m/s and another is just dropped simultaneously.
If the collision between them is elastic, find the time interval between their striking with ground

Two identiacal masses are as shown in figure. One is thrown upwards with velocity 20 m/s and another is just dropped simultaneously. In the above problem, to what maximum height (from ground) with the combined mass rise ?

Two identiacal masses are as shown in figure. One is thrown upwards with velocity 20 m/s and another is just dropped simultaneously. The masses collide I air and stick together. After how much time the combined mass will fall to the gorund (calculate the time from the starting when the motion was started )

" A ball is thrown horizontally and another ball is just dropped simultaneously from the top of a tower.The one that reaches the ground first is "

There are two identical particles A and B. One is projected vertically upward with speed sqrt(2gh) from ground and other is dropped from height h along the same vertical line. Collision between them is perfectly inelastic. Find time taken by them to reach the ground after collision in terms of sqrt(h/g) .
