Answer to Question #107008 in Physics for Ayesha

Question

Q. A parachutist of mass 60 kg falls at a steady speed of 10 m / s. The gravitational field strength g is 10 N / kg.

What is the upward force acting on the parachutist?

A 0N B 6.0 N C 60 N D 600 N

Answer 1

The body moves with constant speed if the net force acting on the body is zero. Hence, the upward force force acting on the parachutist is equal to it weight

$$F=mg=60\:\rm kg\times 10\: N/kg=600\: N.$$
