a 90Kg skier glides down a slope with an incline of 17 degrees, what frictional force...
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 whose mass is 80.0-kg slides down a 5.70º incline as shown. If his velocity is constant, find the value of the coefficient of kinetic friction μ_k between the skis and the snow on the hill. (The component of his weight along the incline will be equal to the frictional force.)
A skier traveling 11.0 m/s reaches the foot of a steady upward 21∘ incline and glides 14 m up along this slope before coming to rest. What was the average coefficient of friction?u= ?
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...

A skier is pulled by a towrope up a frictionless ski slope that makes an angle of 12 degrees with the horizontal. The rope moves parallel to the slope with a constant speed of .0m/s. The force of the rope does 900J of work on the skier as the skier moves a distance of 8.0m up the incline. (a) If the rope moed with a constant speed of 2.0m/s, how much work would the force of the rope do on...
A 24-kg skier slides down a slope angled at 20 degrees relative to horizontal, with a constant speed of 8.0 m/s. a) Draw and label a free body diagram for the skier. b) Find the magnitudes of all forces in your diagram
A 65.0-kg skier is skiing down a 35.0o slope. If the friction force on her ski is 32.0N, what is her acceleration down the slope? Answer: m/s2 What is the normal force on the skier?
A 63 kg skier skis directly down a frictionless slope angled at 20° to the horizontal. Assume the skier moves in the negative direction of an x axis along the slope. A wind force with component Fx acts on the skier. (Indicate the direction with the sign of your answer.) (a) What is Fx if the magnitude of the skier's velocity is constant? N (b) What is Fx if the magnitude of the skier's velocity is increasing at a rate...
••28 A 40 kg skier skis directly down a frictionless slope angled at 10° to the horizontal. Assume the skier moves in the negative direction of an x axis along the slope. A wind force with component F, acts on the skier. What is F, if the mag- nitude of the skier's velocity is (a) constant, (b) increasing at a rate of 1.0 m/s2, and (c) increasing at a rate of 2.0 m/s??
