An Atwood machine is set up with a 14-kg mass held 5.0 m above the ground while a second 8.0-kg mass rests on the ground. The masses are released from rest. Find the the velocity of the 14-kg mass when it hits the ground in two ways, using Newton’s 2nd Law and using conservation of energy. Also, find the maximum height reached by the 8.0-kg mass, assuming it does not hit the pulley
