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 )

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 ?

A sphere A is thrown up with velocity 20m/sec from the ground. Sphere B of same mass is dropped from a height of 80 m simultaneously, at time t = 0 so that both collide in air and stick together. Find the time (in second) after which the combined mass will fall on the ground. (Calculate from t = 0) (g = 10m//"sec"^2)

A particle of mass 1 kg is projected upwards with velocity 60 m/s. Another particle of mass 2 kg is just dropped from a certain height. If, after 2 s, when neither of the particles have collided with ground, the value of the velocity of com (in m/s) is _____

In the example above, after how much time, particle comes to the starting point for the first time. (mass of particle = m)
