Homework Statement



A paratrooper fell 375 m from an airplane without being able to open his chute. Assume that his speed at impact was 52 m/s (terminal speed), that his mass (including gear) was 85 kg, and that the force on him from the snow was at the survivable limit of 1.2 multiplied by 105 N.

a.) What is the minimum depth of snow that would have stopped him safely?

b.)What is the magnitude of the impulse on him from the snow?
