1. For the following, the x-axis is not allowed to be set along the ramp. If a mass, starting from rest, slides along a linear, frictionless incline of length D and then falls a distance h to the ground, will it have an x-component of acceleration? 2. Relevant kinematics formulas? 3. I wasn't certain. It does travel a distance of Dcosθ in the horizontal direction. I initially figured that, because it starts at rest and travels this horizontal distance, there must be some component of acceleration in the x-direction, as well as in the y-direction, but, now, I am uncertain. A similar question with the coordinate axis set similarly also confused me. Thanks!
