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,...
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 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 9.5° with the horizontal. The hillside is 155 m long, and the coefficient of friction between snowand 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 horizontalportion of the snow before coming to rest?____ m
Josh starts his sled at the top of a 2.0 m-high hill that has a constant slope of 25 degrees . After reaching the bottom, he slides across a horizontal patch of snow. The hill is frictionless, but the coefficient of kinetic friction between his sled and the snow is 0.07.
A 66-kg skier starts from rest at the top of a 1200-m-long trail which drops a total of 180 m from top to bottom. At the bottom, the skier is moving 11 m/s.How much energy was dissipated by friction?
A child whose weight is 267 N slides down a 6.10 m long slide that makes an angle of 20.0° with the horizontal. The coefficient of kinetic friction between the slide and the child is 0.100. If the child starts at the top with a speed of 0.457 m/s, what is the child's speed at the bottom? (Ignore air resistance)
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...
A skier starts down a 28 ∘ slope. After a vertical drop of 35 m , the slope temporarily levels out and then drops at 18 ∘ an additional 40 m vertically before leveling out again. The coefficient of kinetic friction on both slopes is 0.15, the level stretches is frictionless. a)What is the skier's speed on the higher level stretch? b)What is the skier's speed on the lower level stretch?
