Question

1. Find the constant D for a 62-kg skydiver with open parachute, such that the terminal velocity is equivalent to that of the skydiver jumbing from a height of 1.4 m without a parachute.

2. For a 1,508-kg car with a drag constant D=0.46 kg/m, which is moving at a speed of 44 mph, what is the magnitude of the maximum acceleration (right at this speed) at which the car can be slowed down. The coeffcicient of kinetic friction is 0.61 and the coefficient of static friction is 0.84.

Calculate the answer to at least 3 significant figures

(Note, this will be the limit due to friction; the real maximum might be further limited by engine power or torque.)

Please show all work.

Explanation / Answer

Drag constant does not contain units.....its dimensionless quantity
