The next two questions share the same information Base your answers to questions 7 and 8 on the information and diagram below. Carts A, B, and C are on a long horizontal frictionless track. The masses of the carts are m, 3m, and 9m. Originally cart B is at rest at the 1.0 meter mark and cart C is at rest on the 2.0 meter mark. Cart A is originally at the zero meter mark moving toward the cart B at a speed of v_{o}

A 0.650 kg ball moving at 5.00 m/s collides with a 0.750 kg ball that is originally at rest. After the collision, the 0.750 kg ball moves of with a speed of 4.00 m/s, and the 0.650 kg ball moves of at a right angle to the final direction of motion of the 0.750 kg ball.

The next two questions share the same information Base your answers to questions 14 and 15 on the information and diagram below. A 3.0 meter long massless rod is free to rotate horizontally about its center. Two 5.0 kg point objects are originally located at the ends of the rod; they are free to slide on the frictionless rod and are kept from flying off the rod by an inflexible massless rope that connects the two objects. Originally the system is rotating at 4.0 radians per second; assume the system is completely frictionless; and ignore any concerns about instability of the system.
