Kaitlyn, whose mass is 60kg, is standing on a roof. What is her weight? She jumps off the roof, what is her acceleration? How long does it take her to fall to the ground if the roof is 8m tall? How fast is she going when she gently hits the ground? If impact lasts 1.2s (stunt person air bag), how much force does she feel? If the impact lasts 0.02s (concrete), how much force does she feel?
