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 speed
without the parachute? Explain.​

Answer 1

Answer:

Hope this may help you

Explanation:

a ) Gravitational force (force of gravity) is the force which is responsible for his downward motion.

b)For the same weight the area will be higher for the person with parachute and hence effective weight or pressure will get reduced resulting in retardation in the motion . ... A man without parachute will always come down with a speed higher than that with a parachute as there will be very rare retardation in the motion.

Answer 2

Answer:

a. Gravity

Force of gravity is responsible for is downward motion and it is a non contact force.

b. No, without the parachute his speed will be higher.
