Consider the simple catapult shown in the figure with an 800 lb counterweight A and a 150 lb 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, neglect the mass of the catapult’s arm, and assume that friction is negligible. The catapult’s frame is fixed with respect to the ground, and the projectile does not separate from the arm during the motion considered.
