Problem 33E

A 62.0-kg skier is moving at 6.50 m/s on a frictionless, horizontal, snow-covered plateau when she encounters a rough patch 3.50 m long. The coefficient of kinetic friction between this patch and her skis is 0.300. After crossing the rough patch and returning to friction-free snow, she skis down an icy, frictionless hill 2.50 m high. (a) How fast is the skier moving when she gets to the bottom of the hill? (b) How much internal energy was generated in crossing the rough patch?

Step-by-Step Solution:

Solution 33E Step 1 of 3: 2 a) vf= v1+ 2gy 12 gsk 2 2 2 2 = (6.5m/s ) + 2(9.8 m/s )(2.5 m) 2(0.300)(9.8 m/s )(3.5 m) = 8.41 m/s
