Consider the catapult shown in the figure with a 1200 kg counterweight A and a 330 kg projectile B. If the system is released from rest as shown, determine the speed of the projectile after the arm rotates (counterclockwise) through an angle of 110°. Model A and B as particles; assume that the catapult’s arm has negligible mass and that friction is negligible. In addition, assume that the cord has negligible mass, is inextensible, and is always vertical. The catapult’s frame is fixed with respect to the ground, and the projectile does not separate from the arm during the motion considered.
