A sled is slowing down at the bottom of a snowy hill. Which statement describes the sled's motion?
The sled has a constant velocity.
The sled is accelerating.
Is a sled slowing down at the bottom of a snowy hill accelerating or constant velocity

A sled and its rider are moving at a speed of along a horizontal stretch of snow, as Figure 4.24a illustrates. The snow exerts a kinetic frictional force on the runners of the sled, so the sled slows down and eventually comes to a stop. The coefficient of kinetic friction is 0.050. What is the displacement x of the sled?
