This deals with a cam follower. The slotted bar rotates with constant angular velocity, theta=12 rad/s. The follower 'A' follows the circular cam as the bar rotates. The arm is pinned at a distance h=0.2m to the left of the cam's center. The radius of the cam is rc=0.42m.
Find the velocity of the follower when theta=40 degrees
a) in terms of polar coordinates
b) in terms of cartesian coordinates
