5-2-1-2 In the figure shown, the slider O may move horizontally, and a hinge at O allows the rod of length L = 1^m to rotate about O. At a certain moment, O is moving to the right at v_O = 0.5^m/s while the rod rotates about O at a rate of omega = 0.5^rad/s. What is the angle theta of the rod if the velocity of A is completely in the x-direction?

Solution

since velocity is perpendicular. for va to be in x direction angle should be 90^o .
