Draw free body diagram including vectors
a) you are riding a bicycle down a hill while applying the brakes and skidding to a stop. assume that air resistance is negligible, but friction is not.

b) you jump off a bridge with a bungee cord attached to your ankle, and the cord stretches. assume air resistance is negligible.

c) a rocket is accelerating straight up through the earth's atmosphere. assume that air resistance is not negligible.

d) a meteoroid moves downward through the earth's atmosphere. its speed is decreasing. assume that air resistance is not negligible.

What is the order of the moon, earth, and sun in a lunar eclipse and a solar eclipse?

Can somebody explain to me how newton's 3rd law relates to momentum? ~ap physics 1

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?
