A man with a parachute jumps at a great height from an airplane moving horizontally. After 10 seconds, he opens his parachute. Find the velocity at the end of 15 seconds and his terminal velocity (i.e., the approximate velocity with chich he will float to the ground). Assume that the combined weight of man and parachute is 160 pounds, and the force of the air resistance us proportional to the first power of the velocity, equaling 4v when the parachute is closed and 10v when it is opened.
