Indicate whether the following statements are true or false. Assume that air resistance is negligible. The speed of the ball was greatest at point Y0 when it was still in contact with the spring. The speed of the ball was decreasing on its way from point Y0 to point Ytop. The speed of the ball was zero at point Ytop. The speed of the ball was the same for all points in its motion between points Y0 and Ytop.

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.
