A 68 kg stunt- woman falls off a bridge and travels 32.0 before colliding with a pile of mattresses. The mattresses are compressed 2.00 m before she is brought to rest. Calculate the magnitude of the average force exerted by the mattresses on the stunt-woman.
PE from top= work at matteresses
68*9.8*(32+2)=force*2
solve for force in Newtons.
