10. Example Problems  11-27. A 36.0-kg child slides down a playground slide that is 2.5 m high. At the bottom of the slide she is moving at 3.0 m/s. How much energy was lost as she slide down the slide?  11-66. A 10-kg test rocket is fired vertically. Its fuel gives it a kinetic energy of 1960 J by the time the rocket engine burns all of the fuel. What additional height will the rocket rise?  Pam, wearing a rocket pack, stands on frictionless ice. She has a mass of 45 kg. The rocket supplies a constant force for 22.0 m and Pam acquires a speed of 62.0 m/s. a. What is Pam’s final kinetic energy? b. What is the magnitude of the force?
