A person with mass 70.0 kilogram jumps out of a window from a fire in his building into the firefighters' net below. The window is 8.0 meter above the net. The firefighters lower their arms as he lands therefore that he is brought to a complete stop in a time of 0.40 second.

A. Find his change in momentum during the 0.40 second interval?

B. Find the impulse on the net due to the boy during the interval? (Do not ignore gravity)

C. Find the average force on the net due to the boy during the interval?
