The first and third quadrants b The union of two intervals d The area inside a parabola End a of the bar moves to the left with a constant velocity a Determine the angular velocity and the angular acceleration a of the bar as a function of its position x A ω, α x hint
You will need to relate to the radius of the semicylinder r using trigonometry, differentiate with respect to t to get vã, and then solve for wa (same goes for acceleration).
