Equations 2.13-2.17 in section 2.6 are derived for the case of a constant acceleration. Suppose that we had an object with an acceleration that increased linearly with time, i. e. a(t) = a0 t. Which of the equations below is not one of the equations of motion for this case? a. v = v0 + ½ a0 t2 b. x = x0 + v0 t + 1/6 a0 t3 c. vf2 = vi2 + 2 a0 ( xf - xi ) d. All of the above are correct equations of motion for this case.

Zeros that follow non-zeros numbers and are also to the right of a decimal point are significant

Anybody wanna ? (picture included? )

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.
