Total weight of the sled and the passenger is 600N. The boy
exerts a constant 180N force at an angle of 300 above the
horizontal. Coefficient of friction between the sled and snow is
0.05. If the initial speed of the sled is 0.1m/s what speed would
it have after being moved a distance of 2m along the ground? Use g
=10N/kg.
