Solve the all parts of following question:
Question: A cookie jar is moving up a 40 ° incline. At a point 56 cm from the bottom of the incline (measured along the incline), the jar has a speed of 1.2 m/s. The coefficient of kinetic friction between jar and incline is 0.11.
Part A: How much farther up the incline will the jar move?
Part B: How fast will it be going when it has slid back to the bottom of the incline?
Part C: Do the answers to (a) and (b) increase, decrease, or remain the same if we decrease the coefficient of kinetic friction (but do not change the given speed or location)?
Please show all intermediate steps and formulas for above question.
