4. A skier starts at the top of a hill with height H, skies down and then climbs a smaller hill. The smaller hill is shaped like a large snowball with a radius R. As the skier skies straight down the side, at what point does she los contact with the snowball and fly off at a tangent: at what angle α does a radial line from the center of the snowball to the skier make with the vertical? Ignore friction.

Please draw diagram and explain

A skier is skiing down a hill on friction-less skies when he realizes there is a cliff in front of him. He skies right over the edge and lands on the valley floor. His motion has two parts: on the hill he started at rest and accelerated throughout his trip. Once he comes to the cliff edge, he goes over the side and is experiencing projectile motion through the air, until he lands. Assume the hill makes a 45 degree...

A skier stands on the top of a giant frictionless snowball with radius R:She is initially at rest, but a slight perturbation starts her sliding off to the side. (a) At what angle with respect to the vertical will she lose contact with the snow? (b) What is the velocity at this point if R = 50 m, and how fast will she be traveling when she hits the ground? The snowball is fixed in place, and doesn't roll.

1. A 85.0-kg speed skier has finished a long down hill race and reaches a final slope (fig. 1 below) designed to slow her down. At the bottom of this slope her speed is 29.0 m/s. She slides up the inclined plane of snow on her skis and at a certain vertical height h has speed 1.95 m/s. The force of friction between her skis and the snow does work of magnitude 3995.0 J . (Ignore air friction.) (a) What...
