A ball is thrown upward with speed 10 m/s from the top to the tower reaches the ground with a speed 20 m/s. The height of the tower is [Take g=10m//s^(2) ]

A stone released with zero velocity from the top of a water, reaches the ground in 4s. The height of the tower is (g = 10 m//s^(2))

A stone is thrown upwards from the top of a tower with some initial speed and it reaches the ground in 16 seconds. Now it is thrown with the same initial speed downward and it reaches the ground in 9 sec . In how much time will it reach the ground if the stone is allowed to fall freely under gravity from the same place ?
