According to the figure, the crank has an angular velocity of 4 rad/s which is constant (C.W). Calculate: A) The velocity of the piston and the angular velocity of the connecting rod. B) The acceleration of the piston and the angular acceleration of the connecting rod. C) The magnitude of acceleration for point M, which is at the middle of the connecting rod. (Apply relative velocity and acceleration analysis. Don't use the method of instantaneous center of rotation.) Note: Write every equation on the paper.
