Question

The figure shows a man with a parachute.
(a) Name the force which is responsible for his
downward motion. Is it a contact force or a
non-contact force?
(b) Will the man come down with the same speedwithout the parachute? Explain.​

Answer 1

1. Force of gravity is responsible for is downward motion and it is a non contact force. Without parachute the man will come down with the faster speed because the parachute creates an air resistance which reduces the speed of the man.
2. The force responsible for his fall is the force of gravity or the gravitational force. Without a parachute, the friction exerted by the man will be less, so he will fall comparatively faster without it.

Answer 2

Answer:

A) gravitational force. it is non contact force

B) No, because this is being done in medium so here mass will act and when he will come down without parachute he will fall with a high speed as compared with the parachute.
