80. A skier starts at the top of a frictionless slope and pushes off with a speed of 2.0 m/s. The elevation of the slope is 45 m. She skis down the slope to a valley with elevation 0.0 m and then glides to the peak of an adjacent slope that is at an elevation of 31 m. Calculate her speed at the second peak.
