A typical raindrop is about 4 mm in the diameter. If a raindrop falls from a cloud which is at 1 km above the ground, estimate its momentum when it hits the ground.
A parachutist drops freely from an aeroplane for 8s before the parachute opens out. Then he descends with a net retardation of 2ms^(-2) reaching the ground with a velocity of 6ms^(-1) . The height from which he bails out of the aeroplane is (g=10ms^(-2))
