4. A box of mass m= 2.0 kg initially at the bottom of a ramp is given a brief hard shove up the ramp with an initial speed vi = 3.00 m/s. The ramp is 1.50 m long and 0.50 m high. The box slides to the very top of the ramp and then slides back down. At the bottom of the ramp, the final speed of the box is vf= 2.00 m/s. How much thermal energy was generated as the box slid up and down the ramp? A) None, the ramp is frictionless. B) 5.0 J C) 1.0 J D) 9.8 J E) None of these. 1.5 m Vi = 3.00 m/s |vr|= 2.00 m/s 0.5 m

1. When a falling object reaches terminal speed, its kinetic energy reaches a constant value. However, the gravitational potential energy of the system consisting of object plus Earth continues to decrease. Does this violate the principle of conservation of energy? Explain why or why not. 2.
