The uniform slender bar AB of mass 10 kg and length 720 mm, is suspended as shown from the 15-kg cart C. Knowing that the system is released from rest and neglecting the effect of friction, calculate and plot the initial acceleration of the cart and the initial angular acceleration of the bar as functions of θ from 0 to 90°.
