Compare the gravitational force on a 33 kg mass at the surface of the earth (with ra-dius 6.4 × 106 m and mass 6 × 1024 kg) with that on the surface of the moon with mass81.3 me and radius 0.27 re. 1what is the force on the earth? answer in units of n.

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?
