Falling with a parachute: If an average-size man jumps from an airplane with a properly opening parachute, his downward velocity v = v(t), in feet per second, t seconds into the fall is given by the following table.

a. Explain why you expect v to have a limiting

value and what this limiting value represents

physically.

b. Estimate the terminal velocity of the parachutist.
