Problenm 044 skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 5.4° 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 780 j of work on the skier as the skier moves a distance of 6.9 m up the incline. (a) if the rope moved with how much work would the force of the rope do on the skier as the skier moved skier when the rope moves with a speed of (b) 1.1 m/s and (c) 2.1 m/s? constant speed of 2.1 m/s, 6.9 m up the incline? at what rate is the force of the rope doing work on the distance (a) number units (b) number units (c) number units

A wave is characterized by the cyclic occurrences of crests and troughs. Wavelengthis defined as the distance between two consecutive troughs or two crests and the Frequency is defined as the number of cycles that pass through a point per second
