Problem 4 [25 pts! In February 1955, a paratrooper fell 370 m from an airplane without being able to open his chute but happened to land in snow, suffering only minor injuries. Assume that his speed at impact was v; = 56 m/s (terminal speed), that his mass (including gear) was 85 kg, and that the magnitude of the constant force on him from the snow was at the survivable limit of 3.2 X M5 N. Find: (a) the minimum depth of snow (cm, round to the nearest integer) that would have stopped him safely (15 pts); (b) time {3, round to 2 decimal places) required for the trooper to pass through this layer of snow before coming to a ll] stop {5 pts); (0) the magnitude of the impulse p (NS, round to 2 decimal places) on him from the snow (5 pts)
