3. The hydraulic cylinder Cextends and causes the collar A to move and accelerate to the left. 3) If the length /= 1.5 ft, the angle 0 = 36°, the linear velocity of collar A, Va is 3.2 ft/s, and the linear acceleration of collar A, aa is 2.4 ft/s?, determine the magnitude of the angular velocity, WAB, of rod AB. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper unit. y Your Answer: Answer units

If the sprocket S is turning with an angular velocity ?S = 6 rad/s, and anangular acceleration of ?S = 2 rad/s^2. Find angular velocity and angular accelerationof link AB. Note that link AB shares an axis of rotation with sprocket S, but is free torotate separately from S (it’s not attached to the sprocket S). The pin at C is attachedto one of the chain links, and is moving vertically downward.
