Assume that his speed at impact was 50 m/s (terminal speed), that his mass (including gear) was 71 kg, and that the magnitude of the force on him from the snow was at the survivable limit of 1.5 x 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?

Answer 1

-XS th: 370 m, 4350 m/s V20, m = 74 Kg a) F = 1.5x105 N as fm = 105x102 v?u- 298 0 = (50)?- 2x1.5x100 71 S = 0.592 m &= 59.2cm b) Infulse = change in momentum I= mw-mul I = 171*(0-50) I = 3550 Nas
