Assume that an arrow having weighs 38.0 g was shot horizontally and consists of a speed of 25.8 m/s when it hits a target which consists of a mass of 0.500 kg. The arrow then fully passes through the target and with the speed of 8.9 m/s.
(i) Assume that the target is at rest if struck; determine what would the speed be after the arrow exits?
(ii) Determine the amount of energy lost as heat in this case?
