Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ķ
=0.381meters and mass ķ=3.1ķķ. initially ķ"is on the ground and ķ#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ķ#just before it strikes the ground. assume the pulley bearing is frictionless.
