Constants A crate of mass M starts from rest at the top of a frictionless ramp inclined at an angle a above the horizontal. Find its speed at the bottom of the ramp, a distance d from where it started. Do this in two ways. Part A Take the level at which the potential energy is zero to be at the bottom of the ramp with y positive upward. Express your answer in terms of the variables M, d, a, and appropriate constants. ΜΕ ΑΣΦ v = Mgd sin (a) Submit Previous Answers Request Answer × Incorrect; The correct answer does not depend on: Mgd, a. Part B ? Take the zero level for potential energy to be at the top of the ramp with y positive upward. Express your answer in terms of the variables M, d, a, and appropriate constants. v = Η ΑΣΦ Submit Request Answer ?
