A4.60 gg coin is placed 19.0 cmcm from the center of a turntable. the coin has static and kinetic coefficients of friction with the turntable surface of μs = 0.820 and μk = 0.440. the turntable very slowly speeds up.1. what is the angular speed in rpm when the coin slides off?

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
