Study this model of a gravitational slingshot. Then answer the questions. In this model, the velocity of the spacecraft at position 2 is the velocity of the craft at position 4. At position 1, the direction of the spacecraft changes because of . Position 3 represents the .

What happens to the light rays when they hit the specimen?

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?
