1. Find the terminal velocity for a 62-kg skydiver. Assume a constant of D=0.25

Question

1. Find the terminal velocity for a 62-kg skydiver. Assume a constant of D=0.25 kg/m. Convert your answer to miles per hour and use mph as units

2. 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.

3. What is the magnitude of the maximum possible acceleration for a car, when the coefficient of static friction is 0.89 and the coefficient of kinetic friction is 0.68? Ingore air drag.

Please show work!!

Explanation / Answer

V = Fg = Fd

mg = 0.25V^2

V = 49.29 m/s = 110.28 mile / hr

2) V = sqrt(2*g*h) = 5.23 m/s

mg= D*v^2 = 22.21 kg /m

c) a = uk*g = 6.664 m/s^2
