Two objects with unequal masses are released from rest from the same height. They slide without friction down a slope and then encounter a rough horizontal region, as shown in Figure 7.43 . The coefficient of kinetic friction in the rough region is the same for both masses. Which of the following statements is or are true? (More than one statement may be true.) Figure 7.43 Multiple-Choice Question 8. A. Both masses start out with the same gravitational potential energy. B. Both objects have the same speed when they reach the base of the slope. C. Both masses have the same kinetic energy at the bottom of the slope. D. Both masses travel the same distance on the rough horizontal surface before stopping. E. Both masses will generate the same amount of thermal energy due to friction on the rough surface.
