Let's say you have two objects in space, attracted to one another by the force of gravity. One has a mass of m, and the second has a mass of 5m. How does the force of gravity on the first mass compare to the force of gravity on the second, more massive, object?

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
