A car falls off a ledge and drops to ground in 0.5s. Let g = 10 ms^-2 How high is the ledge from the ground?

A ball dropped from a height 'h' reaches the ground in time 'T'. What is its height from the ground at time T/2 ?

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

It is well known that a rain drop falls under the influence of the downward gravitational force and the opposing resistive force. The latter is known to be proportional to the speed of the drop, but is otherwise undetermined. Consider a drop of mass 1.0g falling from a height of 1.00km. It hits the ground with a speed of 50.0ms^(-1) (b) What is the work done by the unknown resistive force ?

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 body of mass 5 kg is dropped form a height o 1 m. Its kinetic energy just before reaching the ground is

If the speed of sound in air at 0^C is 331 ms^(-1) . What will be its value at 35^@C ?
