(There could be more than one correct choice. )

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