A 50.0 kg object slides down a 30o angle slope from rest at a height of 12.0 m. The coefficient of kinetic friction between the object and the slope surface is 0.20.
(A) What is the object's speed at the bottom of the slope?
(B) If the object continues to slide on the level ground after reaching the bottom, and if the ground's coefficient of friction is the same as the slope, how far will the abject move before stopping?
