The sliders shown below are confined to move in the horizontal and vertical slots. If the velocity of slider A is 10 ms¯¹ and its acceleration is 10sqrt(2) ms-². Calculate the angular acceleration, in rad/s², of the connecting bar when theta = 45 deg. Round your answer to the nearest integer. Add your answer B 0 2m A VA 10 m/s

A cylinder of radius 7 = 0.2 m is about to start rolling down an inclined plane. The acceleration of the center of the cylinder is 9.81 sin(0) m/s?. The angular acceleration is 9.81 sin(0)/r rad/s?. Assume 0 = 0.8 rad. What is the magnitude of acceleration of the point on the cylinder furthest from the inclined plane in m/s?. Hint: Since it is about to start rolling, the velocity of the center of the cylinder and angular velocity of the cylinder are still zero at that instant.
