As part of a project for his biology class, Alex is studying the motion of a turtle over the course of an hour. He places the turtle at the center of a
circular tank. After a few minutes, the turtle hasn't moved and Alex ends up
drifting off to sleep. When Alex wakes up at the end of the hour, the turtle is
still at the center of the tank. Which of the following can Alex conclude about
the turtle's motion during the hour?

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?
