Asled is being held at rest on a slope that makes an angle ΞΈ 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 ΞΌk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionΞΌk. express your answer in terms of someor all of the variables d1, d2, and ΞΈ.
