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)`

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 )

Body A of mass M is dropped from a height of 1 m and body. B of mass 3M is dropped from a height of 9 m. The ratio of time taken by the bodies 1 and 2 to reach the ground is

A ball is gently dropped from a height of 20m . If its velocity increases uniformly at the rate of 10 m//s^(2) , with what velocity will it strike the ground ? After what time will it strike the ground ?

A ball of mass 100 gm is projected vertically upwards from the ground with a velocity of 49m//sec . At the same time another identical ball is dropped from a height of 98 m to fall freely along the same path as that followed by the first ball. After some time the two balls collide and stick together and finally fall to the ground. Find the time of flight of the masses.
