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 the ramp and the end of the rough patch. calculate the time intervals it takes the skier to reach the bottom of the ramp and the end of the rough patch. sketch the velocity graph for this motion.

    A skier, starting from rest, coasts down a slope that makes a 25.0o angle with the horizontal. The coefficient of kinetic friction between the snow and the skis is 0.200. The skier travels along the slope a distance of 11.4 m before skiing off the edge of a cliff. The skier falls a vertical distance of 3.80 m before landing on another downhill slope. Determine the speed with which the skier lands.

    An extreme skier, starting from rest, coasts down a mountain slope that makes an angle of 25.0° with the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.200. She coasts down a distance of 12.1 m before coming to the edge of a cliff. Without slowing down, she skis off the cliff and lands downhill at a point whose vertical distance is 2.60 m below the edge. How fast is she going just before she...

    An extreme skier, starting from rest, coasts down a mountain slope that makes an angle of 25.0° with the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.200. She coasts down a distance of 10.9 m before coming the edge of a cliff. Without slowing down, she skis off the cliff and lands downhill at a point whose vertical distance is 2.60 m below the edge. How fast is she going just before she lands?...

    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...

    A skier going down a slope of angle θ below the horizontal is opposed by a turbulent drag force that the air exerts on the skier and by a kinetic friction force that the snow exerts on the skier. The mass of the skier is m. Determine the terminal speed assuming that the coefficient of kinetic friction between the skis and the snow is μ, the density of air is ρ, the skier's frontal area is A, and the drag...

    A 49 kg skier skis directly down a frictionless slope angled at 11° to the horizontal. Choose the positive direction of the x axis to be downhill along the slope. A wind force with component Fx acts on the skier. What is Fx if the magnitude of the skier's velocity is (a) constant, (b) increasing at a rate of 1.4 m/s2, and (c) increasing at a rate of 2.8 m/s2. Use g = 9.81 m/s2.
