Problem 3. A flat surface follower behaves in the following manner. There is a constant acceleration ascent for 60°, followed by 60° of constant velocity, and finally constant deceleration for 60°. The follower rests for the next 45° before beginning its descent, which is cycloidal for the rest of its trajectory. Determine the equations for each section. Take Smax as 100 cm.

Problem 4 A uniform solid spherical ball of mass M and radius R rests on a horizontal surface. Assume a constant coefficient of friction (this means that the frictional force is equal to the normal force multiplied by u). The acceleration due to gravity is g. At time t 0, the bal is struck impulsively on center, causing it to go instantaneously from rest to initial rotation horizontal speed vo with a no (a) Find the horizontal speed, and the...
