Problem: A 10 kg object slides down an incline of 30 o. If the object starts at a height of 30 cm, and feels a coefficient of kinetic friction of 0.2 down the slope, answer the following questions:a. How much work is done on the object as it moves down the slope?   b. What is the change in the object’s potential energy down the slope?    c. What is the change in the object’s kinetic energy down the slope
