A skier starts at the top of a very large, frictionless snowball, with a very small initial speed, and skis straight down the side (Fig. P7.63). At what point does she lose contact with the snowball and fly off at a tangent? That is, at the instant she loses contact with the snowball, what angle α does a radial line from the center of the snowball to the skier make with the vertical? Figure P7.63

A skier starts from rest at the top of a hill. The skier coasts down the hill and up a second hill, as the drawing illustrates. The crest of the second hill is circular, with a radius of 33.6 m. Neglect friction and air resistance. What must be the height h of the first hill so that the skier just loses contact with the snow at the crest of the second hill? Number Units

A block with a mass m = 2.34 kg is placed at the top of a hinged incline plane with a length L = 1.47 m. The angle the plane makes with the horizontal is slowly increased. The block starts to slide when θ = 24.8∘. The coefficient of kinetic friction between the block and the plane is μk = 0.338. Part 1) What is the coefficient of static friction between the block and the plane? μs = Part 2) What is the net force on the block as it slides down the inclined plane (when it is inclined at θ = 24.8∘)? Fnet = N down the plane Part 3) What is the speed of the block at the bottom of the inclined plane (it starts from rest at the top of the plane)? v = m/s
