If we model the drag force of the atmosphere as proportional to the square of the speed of a falling object, Fdrag = ?bv^2, where the value of b for a 83-kg person with a parachute is 17 kg/m.
(a) What is the person's terminal velocity?
(b) Without a parachute, the same person's terminal velocity would be about 54 m/s. What would be the value of the proportionality constant b in that case?
