A Heavy Sled and a Light Sled, Both Moving Horizontally

question 127

Multiple Choice

A heavy sled and a light sled, both moving horizontally with the same kinetic energy, suddenly slide onto a rough patch of snow and eventually come to a stop. The coefficient of kinetic friction
Between the sleds and the rough snow is the same for both of them. Which of the following
Statements about these sleds are correct? (There could be more than one correct choice.)

• A) The light sled will slide farther on the rough snow than the heavy sled.
• B) Both sleds will slide the same distance on the rough snow before stopping.
• C) On the rough snow, the change in kinetic energy will be the same for both sleds.
• D) The heavy sled will slide farther on the rough snow than the light sled.
• E) The friction from the snow will do the same amount of work on both sleds.
