[SOLVED] Impulse and depth********!
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 58 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 1.2 105 N.
(a) What is the minimum depth of snow that would have stopped him safely?
?m
(b) What is the magnitude of the impulse on him from the snow?
? kg·m/s
I have no clue how to do this problem
I DONT KNOW. i am in desparate need of help.
ANY CLUES or ANY hints will help.
THANK YOU!*****************
