Rotation of the radially slotted arm is governed by θ=0.2t+0.02t3 where θ is in radians and t in seconds. Simultaneously, the power screw in the arm engages the slider B and controls its distance from O according to r=0.2+0.04t2, where r is in meters and t in seconds. Solve for the x component of radius, in m, when t=3 secs. Round your answer to 3 decimal plac

When block B is resting on the surface, pulley A is rotating at a constant angular acceleration α = 6 rad/s². Pulley C has an inner hub D which are turning together as one body. Assuming the belt is inextensible and does not slip What is the speed of block B, in m/s, when it is at 6 m above the surface? Round the answer to two decimals. 50 mm A 75 mm 150 mm C B
