Question
An 85 kg paratrooper once fell 370 m from an airplane without a working parachute. He landed in snow and suffered only minor injuries. Assume that the speed at impact was 56 m/s, terminal velocity, and that the force on him by the snow was at the survivable limit of 1.2×1051.2×105 N. What is the magnitude of the impulse on him from the snow? Enter your answer in kg m/s, but do not enter units.

Answer:
Explanation:
The final velocity is zero
The mass:
Now we can apply impulse relationship which stated that:
Δp=mΔv
Δp=
substitute the values
Δp
Δp
