A parachutist flying in an aeroplane jumps when it is at a height of 3 km above ground. He opens his parachute when he is about 1 km above ground. Describe his motion.

A man whose mass is m kg jumps vertically into air from the sitting position in which his centre of mass is at a height h_(1) from the ground. When his feet are just about to leave the ground his centre of mass is at height h_(2) from the ground and finally centre of mass rises to h_(3) above the ground when he is at the top of the jump. what is the average upward force exerted by the ground on him?

An aeroplane is flying with a velocity of 216 km/h at an altitude of 1960 m relative to the ground. It drops a bomb when it is just above a point A on the ground . The bomb hits the ground at B. The distance AB is

A bomb of mass 40 kg is dropped from an aeroplane at a height of 1 km above the ground. What is its kinetic energy (i) at the end of 10 s and (ii) on reaching the ground ?

An aeroplane is flying in a horizontal direction with a velocity 600 km//h at a height of 1960 m. When it is vertically above the point A on the ground, a body is dropped from it. The body strikes the ground at point B. Calculate the distance AB.
