At a poorly-designed ski resort, there is a flat cross-country ski trail right next to a 21-meter high curved downhill ski hill. A 100-kg man is coasting on the cross-country trail (without friction) at a constant speed of 2.5 m/s. A woman starts from rest at the top of the downhill course and slides (without friction) to the bottom, where she collides with the man. The tangle of people and skis together slides away at 10 m/s. What was the mass of the woman?

Need the exercise portion Hit the Ski Slopes EXAMPLE 5.8 GOAL Combine conservation of mechanical energy with the work-energy theorem involving friction on a horizontal surface. h = 20.0 m у A skier starts PROBLEM from rest at the top of a frictionless incline of height (В С) 20.0 m, as in the figure. At the bottom of the incline, the skier The skier slides down the slope and onto a level surface, stopping after encounters a horizontal traveling a...
