A stunt person whose mass is 625 kg falls from rest, Ask an Expert

Academics

A stunt person whose mass is 62.5 kg falls from rest vertically downward a distance of 8.10 m.

The person's fall is not 'free-fall' due to air resistance. The person's speed is 10.5 m/s just before hitting an air bag (that stops the fall).

A) Determine the change in the kinetic energy of the person during the stunt.

B) Determine the work done by the force of gravity on the stunt person.

C) Determine the total work done on the stunt person.

D) Determine the work done by air resistance on the stunt person.
