A skier begins at the top of a 10.9-degree-inclined slope. The slope is 220 metres long, with a coefficient of friction of 0.0750 between snow and skis. The snow is flat at the bottom of the slope, and the coefficient of friction remains constant. How far down the horizontal area of the snow does the skier glide before coming to rest?
A 25 N block starts from rest and slide 9 m down a roof with a slope of 2 horizontal to 1 vertical and a coefficient of friction of 0.10. If the vertical distance from the edge of the roof to the ground is 12 m, what is the distance from the wall that the ball will strike the ground?
A 2 kg box is put on the surface of an inclined plane at 27 degrees with the horizontal. The kinetic coefficient of friction is μ = 0.3. If released from rest at a height of 3 meters, how long would it take the box to reach the bottom?
