A man drops a 10 kg rock from the top of a 5 m ladder. What is its speed just before it hits the ground ? What is its kinetic energy when it reaches the ground ? (`g = 10 m//s^(2)`)

A man drops a 10 kg rock from the top of a 20 m ladder. What will be its kinetic energy when it reaches the ground ? What will be its speed just before it hits the ground ? Does the speed depend on the mass of the rock ?

A ball of mass 200 g falls from a height 5 metres. What is its kinetic energy when it just reaches the ground ? ( g = 9.8 m//s^(2) ).

A ball of mass 200 g falls from a height of 5 m. What will be its kinetic energy when it just reaches the ground ? (g=9.8ms^(-2))

A body of mass 10 kg is kept at a height of 5 m. It is allowed to fall and reach the ground. What is the kinetic energy possessed by the body just before hitting the ground? (Take g = 10m//s^(2) ).

A stone is dropped from a height of 20 m . (i) How long will it take to reach the ground? (ii ) What will be its speed when it hits the ground? (g= 10 m//s^2)

A man drops a 20 kg object from the top of a 10m high building . What will be the velocity of the object when it just hits the ground?

A body of mass 10 kg falls from a height of 10 m. What will be its kinetic energy just before it touches the ground ? Prove that, this kinetic energy is equal to the potential stored at the initial position of the body. [g=980 cm *s^(-2) ]

A mass of 10 kg is dropped form a height of 50 cm. Find its kinetic energy just on touching the ground.
