The slotted arm OA rotates counterclockwise about O such that when = /4, arm OA is

The slotted arm OA rotates counterclockwise about O such that when θ = π/4, arm OA is rotating with an
angular velocity of θ̇ and an angular acceleration of 0.
Determine the magnitudes of the velocity and
acceleration of pin B at this instant. The motion of pin B is
constrained such that it moves on the fixed circular
surface and along the slot in OA.
