An angry student (upset over his mid-term mark) throws an orange at his TA. The orange (m = 160 g) hits the TA in the head and comes to rest in 0.06s.

Question

If the skull can undertake a force of 1100N before the brain is damaged, how fast must the orange be traveling?

Answer 1

force*timeimpact= changemomentum
force=1100*.06=.160V

V=1100*.06/.160 m/s
