Question

A parachutists of mass 60kg falls with a constant velocity of 5m/s together with a parachute of mass 20kg. Taking g to be 10N/Kg what is th resultant force on the system?

Answer 1

Answer.

Net force=0

Explanation.

F = ma

m = 80kg

$a = 0 \: m \: per {s}^{2}$

Since constt velocity

F = ma

Therefore F=0
