Askydiver of mass m jumps from a hot air balloon and falls a distance d before reaching a terminal velocity of magnitude v. assume that the magnitude of the acceleration due to gravity is g. part a what is the work wd done on the skydiver, over the distance d, by the drag force of the air? express the work in terms of d, v, m, and the magnitude of the acceleration due to gravity g.

The work done by the drag force on the skydiver over the distance is  .

Further Explanation:

The skydiver dives from the hot air balloon and falls freely under gravity and attains the terminal velocity. The skydiver attains the kinetic energy and some of the energy attained is lost in overcoming the drag force.

The amount of energy lost by the skydiver is the work done by the drag force.

The kinetic energy of the skydiver as he falls with speed is:

The potential energy lost by the skydiver due to the decrease in height is:

Therefore, according to work energy theorem, the amount of work done by drag force is equal to the change in energy.

Here, is the work done by the drag force.

Substitute the values of and in above expression.

Thus, the work done by the drag force on the skydiver over the distance is
