The slotted link is pinned at O, and as a result of the constant angular velocity  it drives the peg P for a short distance along the spiral guide r = (0.4 θ) m, where θ is in radians. Determine the velocity and acceleration of the particle at the instant it leaves the slot in the link, i.e., when r = 0.5 m.
