A man with a parachute jumps at a great height from an airplane moving horizontally. After 10 seconds, he opens his parachute. Find his velocity at the end of 15 seconds and his terminal velocity (i.e., the approximate velocity with which 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 is proportional to the first power of the velocity, equaling 4v when the parachute is closed and 10v when it is opened

You testify as an expert witness in a case involving an accidentin which car A slid into the rear of car B, which was stopped ata red light along a road headed down a hill.
