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 56 m/s (terminal speed), that his mass (including gear) was 61 kg, and that the magnitude of the force on him from the snow was at the survivable limit of 1.3 × 105 N. What are (a) the minimum depth of snow that would have stopped him safely and (b) the magnitude of the impulse on him from the snow? (a) Number i Units (b) Number i Units

By comparing the surface area of a sphere with its volume and assuming that air resistance is proportional to the square of velocity, it is possible to make a heuristic argument to support the following premise: For similarly shaped objects, terminal velocity varies in proportion to the square root of the length. Expressed in a formula, this is T = kL0.5, where L is length, T is terminal velocity, and k is a constant that depends on the shape, among other things. This relation can be used to help explain why small mammals easily survive falls that would seriously injure or kill a human. (Round your answers to two decimal places.)
