Question

7) [Horizontal-ish] A box slides down a ramp (with some friction) onto a frictionless level surface starting from rest, hits a rubber wall, and bounces back to near the original position but not quite as far. For ease of conveying the answer, feel free to use the following notation: A-the initial position of the box on the ramp B = the position just after the box transitions from ramp to level surface while moving to the right (occurs at the first moment when the box is completely on the level surface) C the position at which the box first touches the rubber wall while still moving right D = the position at which the box pushes the wall its farthest E-the position just before the box stops touching the rubber wall while moving left F = the position just before the box transitions from the level surface to the ramp while still moving left (occurs at the last moment when the box is completely on the level surface) G = the position at which the box stops on the ramp Assume the box does not change its shape Let the +direction be down the ramp and to the right. Let the position 0 at the point where the box is just barely touching the wall Rubber Wall Ramp CD Level Surface For each of the following situations, write down the parts of the box's movement from A to G with the situations, below. Ifa situation can not happen, then write "N/A". a) +Acceleration, a>0 b) 0 Acceleration, a 0 c) -Acceleration, a 0 e) 0Velocity, v=0 f) Velocity, V0 h) 0 Displacement, =0 i) - Displacement, Ax0 k) 0 Position, x=0 -Position,
