8. A skier of weight 150 lbs starts at the top of a mountain 100 m high, and slides down its slope of 30° with a coefficient of kinetic friction of 0.03. How long does it take the skier to reach the bottom of the mountain.
A skier wants to reach a speed of 14 m/s at the bottom of a slope of length L inclined at an angle of 30° with respect to the horizontal. If the skier starts from rest, what is the minimum L required to reach this velocity? 28 m 20 m 14 m 10 m 5 m
A skier is gliding along at 3.0 m/s on horizontal, frictionless snow. He suddenly starts down a 10∘ incline. His speed at the bottom is 11 m/s . A) What is the length of the incline? Express your answer with the appropriate units. B)How long does it take him to reach the bottom? Express your answer with the appropriate units.
a skier starting from rest down a snow slope that makes 18 degrees with the horizontal. He starts from the height of 8 m. at the bottom of the slope is a 9 m long rough horizontal surface. the acceleration slowing the skier down on the rough patch has a magnitude of .8m/s2. what is the skier's speed when he reaches the end of the rough patch? calculate the time intervals it takes the skier to reach the bottom of...
3. A skier is at the top of a slope 50m (the vertical height) above the base of the slope with an initial speed of 7m/s. The slope is inclined 35 degrees above horizontal and has a coefficient of kinetic friction of 0.2. What will her speed be at the bottom of the incline? a. 28.8 m/s b. 26.5 m/s c. 27.4 m/s d. 36.2 m/s e. 32.1 m/s

A skier slides down a slope at an incline of 30 degrees. It takes 12 s for the skier to reach the bottomr of the slope. Assume motion is frictionless descent. How long is the slope? What is the skier’s velocity when he reaches the bottom of the slope?
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?
