At the instant θ = 30°, the cam rotates with a clockwise
angular velocity of θ̇ = 5 rad/s and angular acceleration of θ̈ = 6 rad/s². Determine the magnitudes of the velocity and acceleration of the follower rod AB at this instant. The surface of the cam has the shape of a limaçon defined by r = (200 + 100 cos θ) mm.

r = (200 + 100 cos 0) mm A B
