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 skier of mass 72 kg is pulled up a slope by a motor-driven cable. (a) How much work is required to pull him 85 m up a 30 degree slope (assumed frictionless) at a constant speed of 2.2 m/s? Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. (b) What power (expressed in hp) must a motor have to perform this task? Your response differs significantly from the correct...
A skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 8.9° with the horizontal. The rope moves parallel to the slope with a constant speed of 1.1 m/s. The force of the rope does 640 J of work on the skier as the skier moves a distance of 5.9 m up the incline. (a) If the rope moved with a constant speed of 2.4 m/s, how much work would the force of...

A skier is pulled up a slope at a constant velocity by a tow bar. The slope is inclined at 25.2 ° with respect to the horizontal. The force applied to the skier by the tow bar is parallel to the slope. The skier's mass is 46.5 kg, and the coefficient of kinetic friction between the skis and the snow is 0.158. Find the magnitude of the force that the tow bar exerts on the skier.
A skier of mass 70kg is pulled up a frictionless incline of 30 degrees for 60m along the incline attaining a speed of 2m/s. How much energy is required to perform that action by the motor? B) calculate power
Question 13 13 pts A box of mass 0.8 kg is being pulled up a slope that is inclined by 60° compared to the horizontal. The tension in the rope pulling the box is 40 N and the rope is parallel to the incline. The slope is NOT frictionless and the coefficient of kinetic friction between the box and the slope is 0.35. Round off your answers to two decimal places. (a) What is the magnitude of the weight of...
