An 800.0 kg roller coaster car is at rest at the top of a 95 m hill. It rolls down the first drop to a height of 31 m. When it travels to the top of the second hill, it is moving at 28 m/s. It then rolls down the second hill until it is at ground level. Draw a picture of the roller coaster drop and calculate the kinetic and potential energy at the top and bottom of each hill.

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.
