62.00 kg skier starts at the top of a small hill of heigh h-6.500m. Starting from rest she uses her poles to push her along a flat surface for(d= 12.00 m)with a constant force of 130.0 N She then stops pushing and coasts over the edge and down the hill. Assuming the small amount of friction from the snow does 480.0 J of work from when she starts pushing until she gets to the bottom of the hill, how fast is she going at the bottom of the hill? (use g-9.80 m/s2 for these calculations.)Explanation / Answer
Net work done by her from start to reach ground = Fd+ mgh =130*12+62*9.8*6.5 = 5509.4 J
Work energy method,
0.5 mv^2 =5509.4
V= 13.33 m/sec ( ans)
