4. A sled is pulled horizontally across the snow at constant velocity. The pulling force is 40 N.
(Remember: Constant velocity means zero external forces)
a. What is the kinetic Frictional Force on the Sled?
b. if the weight of the sled is 200 N, what is the co-efficient of Kinetic Friction (us) between
the sled and snow?
c. If wood, weighing 300 N is placed in the sled, what pulling force is needed to move the
sled at constant velocity?
