Some sliding rocks approach the base of a hill with a speed of 17.0 m/s . The hill rises at 42.0 ∘ above the horizontal and has coefficients of kinetic and static friction of 0.450 and 0.550, respectively, with these rocks. Start each part of your solution to this problem with a free-body diagram. Find the acceleration of the rocks as they slide up the hill. Once a rock reaches its highest point, will it stay there or slide down...

Now we are going to look at the problem of an object sliding down a frictionless inclined plane. Suppose a toboggan loaded with vacationing students (total weight w) slides down a long, snow-covered slope. The hill slopes at a constant angle α, and the toboggan is so well waxed that there is virtually no friction. Find the toboggan’s acceleration and the magnitude n of the normal force the hill exerts on the toboggan. At what angle does the hill slope...
