If a ball is dropped from height 2 metre on a smooth eleastic floor, then the time period of oscillation is

A lift is moving with uniform downward acceleration of 2 m//s^(2) . A ball is dropped from a height 2 metre from the floor of lift. Find the time after which ball will strike the floor.

A body dropped from a height h into the floor makes elastic collision with the floor. The frequency of oscillation of its periodic motion is

In a lift moving up with an acceleration of 5 m s^(-2) , a ball is dropped from a height of 1.25 m. The time taken by the ball to reach the floor of the lift is ……(nearly) ( g = 10 ms^(-2) )

A ball is dropped from a height h . As it bounces off the floor, its speed is 80 percent of what it was just before it hit the floor. The ball will then rise to a height of most nearly

A ball is dropped from a height h. As it bounces off the floor, its speed is 80 per cent of what it was just before it hit the floor. The ball will then rise to a height of most nearly:
