KE₁ O yes A 70.0000-kg skier with an initial speed of 10.0000 m/s coasts up a 2.5000-m-high rise as shown in the figure. The coefficient of friction between her skis and the snow is 0.0800. Hint: find the distance traveled up the incline assuming a straight-line path as shown in the figure. Think & Prepare 1. Make note of what's given and what's unknown. Relate known quantities to symbols. 2. Draw a labeled sketch if possible. 4. Insert numerical quantities to solve for unknowns. 5. Does the answer make sense? (a) Is mechanical energy conserved in this problem? V₁ 3. Identify the physics principle and approach. Write down relevant equations symbolically. Simplify if possible. O zero O no (b) The change in mechanical energy equals O work done by friction. 35° O increase in PE. (c) The work done by friction is 2.5 m
