FIRE EMERGENCY A girl of mass 48.0 kg is rescued from a building fire by leaping into a firefighters' net. The window from which she leapt was 12.0 m above the net. She lands in the net so that she is brought to a complete stop in 0.45 s. During this interval (a) What is his change in momentum? (b) What is the impulse on the net due to the girl? (c) What is the average force on the net due to the girl?
