Work, Power and Energy TEST 11. A rolling bowling ball knocks over a single pin. The pin goes flying, and the baill continues rolling but at a slower speed. Which of the following statements best describes the change in energy necessary for the bowling ball to do work on the pin? A The ball does work on the pin by transferring all of its kinetic energy to the pin. B All the potential energy of the ball is converted to work on the pin. C The ball does work on the pin by transferring some of its kinetic energy to the pin D Some of the potential energy of the ball is converted to work on the pin. 12. A ball is dropped from the top of a iliff. Which graph best represents the ball's total energy as the ball falls to the ground if air resistance is ignored? C Total Energy Total Energy Time Time Total Energy Total Energy Time Time 13. Which correctly identify the change in energy as Pluto (the dwarf planet) orbits from location S to location Q? Given that velocity increases from $ to Q KE increases KE decreases KE remains the same D Not enough information provided 14. How much work is done on a 50.0 kg downhill skier when an average braking force of 7.8 x 10# newtons is applied to the skier to stop her over a distance of 10.0 meters? A 10 x 10 J B 7.8 x 10 ] C 10 x 10' J D 7.8 x 10' )
