a 20-kg child descends a slide 3.0 m high and reaches a speed of 2.4 m/s when she hits the bottom. how much thermal energy due to friction is generated during the process?

What is created when solids,liquids,an gases mix with one another

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
