Two forces act on a parachutist falling in air: weight and air drag.If the fall is steady, with no gain or loss of speed ,then the parachutist is in dynamic equilibrium. How do the magnitudes of weight and air drag compare?

Step 1

The rate of change of velocity is known as Acceleration. Means, if velocity is constant or steady with respect to time then there will not be any acceleration.

As in the given situation, the parachutist is in dynamic equilibrium and there is no gain or loss of speed, so the acceleration of the parachutist is zero. Therefore,...
