Problem
A 40 kg sled is released from rest at the top of a frictionless snow-covered slope that is straight and inclined at 30° to the horizontal. The sled travels 12 m along the slope.
(a) Determine the sled’s speed after it has traveled 6.0 m along the slope.
(b) Calculate the instantaneous power delivered by the gravitational force to the sled at the moment it has traveled the 6.0 m distance.
