60f10 -/1 ;= View Policies Current Attempt in Progress Holding onto a tow rope moving parallel to a frictionless ski slope, a 78.8 kg skier is pulled up the slope, which is at an angle of 6.70" with the horizontal. What is the magnitude FmIDe of the force on the skier from the rope when (a) the magnitude v of the skier's velocity is constant at 1.67 m/s and (b) v = 1.67 m/s as v increases at a rate of 0.120 m/sz
