Suppose a skydiver of mass m jumps out of a stationary helicopter far above the Earth. As he falls, he experiences an upward drag force Fp = b, where b is a constant (the de find drag coefficient), and v is his velocity. Recalling that the acceleration is a = his velocity as a function of time, v(t), assuming that he started from rest. What is his terminal velocity? Hint: You might find the following identities useful: 1 1 v2-a 2a v-a v+a where a is any constant, and also In A - In B = In (4).
