In February 1955, aparatrooper fell 370 m from anairplane without being able to open his chute but happened to landin snow, suffering only minor injuries. Assume that his speed atimpact was 60 m/s (terminal speed),that his mass (including gear) was 80kg, and that the force on him from the snow was at the survivablelimit of 1.2 105 N.
(a) What is the minimum depth of snow that would havestopped him safely?
m
(b) What is the magnitude of the impulse on him from the snow?
kgm/s
