The *ABCD* rod shown rotates on two spherical joints in *A* and *D*, in a clockwise
direction when viewed from the point of view *A*. The angular speed of the bar at the instant
considered is equal to 12 rad/s, and decreases at the rate of 3 rad/s^{2}. Find:

a) The angular velocity, in rad/s;

b) The angular acceleration, in rad/s^{2};

c) The velocity of point*B*, in em m/s;

d) The acceleration of point*B*, in m/s^{2}.

a) The angular velocity, in rad/s;

b) The angular acceleration, in rad/s

c) The velocity of point

d) The acceleration of point
