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 lose 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....

A skier starts from rest at the top of a hill that is inclined at 10.0° with respect to the horizontal. The hillside is 250 m long, and the coefficient of friction between snow and skis is 0.0750. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How far does the skier glide along the horizontal portion of the snow before coming to rest?

A skier starts from rest at the top of a hill that is inclined at 9.8° with respect to the horizontal. The hillside is 240 m long, and the coefficient of friction between snow and skis is 0.0750. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How far does the skier glide along the horizontal portion of the snow before coming to rest? m

A skier with mass 64.0 kg starts at rest at the top of an 842 m long ski slope, which makes an angle 13.0 ∘ with the horizontal. A typical coefficient of friction between skis and snow is 5.20×10−2. skiers don't go straight down the hill- they zigzag back and forth. Even though they still end up at the bottom of the hill, they've lost more energy to friction because friction is a non-conservative force. Let's say due to zigzagging,...

H 11. A skier of mass 82 kg starts a downhill run from the top of a straight hill. The hill has a rough surface and has a length of 112 m. The top of the hill is 37.5 m above the lowest point. The speed of the skier at the top of the hill is - 183 and coefficient of kinetic friction between the skier's skis and the hill is 0.12. How fast is the skier moving at the...

An 90 kg skier starts from rest at the top of a ski run. She quickly finds herself going fast down the icy (essentially frictionless) hill. At the base of the hill she is unable to stop. She skis across an icy deck, through the open doors of the ski lodge; across the concrete floor of the rental shop before coming to rest against the back wall of the shop. The height of the hill is 150m, the deck and...

A roller coaster starts from rest at the top on the hill and begins to roll from point 1 to point 2. Assuming no friction Answer the following questions. Is the energy of the roller coaster conserved in this problem? Explain your reasoning. Find the speed of the roller coast as it passes through point 2. Find the speed of the roller coast as It passes through point 3. Find the speed of the roller coast as it passes through...

Problem 9 m,r A solid ball of mass m and radius r sits at rest at the top of a hill of height H leading to a circular loop-the loop. The center of mass of the ball will move in a circle of radius R if it goes around the loop. The moment of inertia of a solid ball is Ibull--mr. (a) Find an expression for the minimum height H for which the ball barely goes around the loop, staying...

1) A solid ball of mass M and radius R rolls without slipping down a hill with slope tan θ. (That is θ is the angle of the hill relative to the horizontal direction.) What is the static frictional force acting on it? It is possible to solve this question in a fairly simple way using two ingredients: a) As derived in the worksheet when an object of moment of inertia I, mass M and radius R starts at rest...
