question 187

Multiple Choice

A heavy sled and a light sled,both moving horizontally with the same speed,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)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)The friction force exerted on the sled by the snow will do more negative work on the heavy sled than on the light sled.
• E)The friction force exerted on the sled by the snow will do the same amount of work on both sleds.
