A 62.0kg skier on level snow coasts 164m to a stop from a speed of 1.40m/s.
A. Use the work-energy principle to find the coefficient of kinetic friction between the skis and the snow.
B. Suppose a 73.0kg skier with twice the starting speed coasted the same distance before stopping. Find the coefficient of kinetic friction between that skier's skis and the snow.
A 1540.0 g mass is ona horizontal surface with μk = 0.31, and isin contact with a massless spring with a force constant of 787.0N/m which is compressed. When the spring is released, it does 2.52J of work on the mass while returning to its equilibr..
