Question

A parachutist diving from an aeroplane from

rest experiences an acceleration of g exp(— kt).

Obtain expression for the distance travelled by

the parachutist in time t given that x(t = 0) = x 0.​

Answer 1

Answer:

In order for the parachute model to give a terminal velocity of 15 miles per hour, the drag coefficient must be approximately k/m = 3/2. Without the parachute, the skydiver can reach speeds of over 45 miles per hour, which corresponds to a drag coefficient k/m < 1/2
