Aservomotor controls the vertical movement of a drill bit that will drill a pattern of holes in sheet metal.The maximum vertical speed of the drill bit is 4 in./s, and while drilling the hole, it must move no more than2.6 in./s to avoid warping the metal. During a cycle, the bit begins and ends at rest, quickly approaches the sheet metal, and quickly returns to its initial position after the hole is drilled. Sketch possible graphs of thedrill bit’s vertical velocity and acceleration. Label the point where the bit enters the sheet metal.
