X = 0 A person with mass m1 = 52 kg stands at the left end of a uniform beam with mass m2 = 105 kg and a length L = 3.3 m. Another person with mass m3 = 59 kg stands on the far right end of the beam and holds a medicine ball with mass m4 = 9 kg (assume that the medicine ball is at the far right end of the beam as well). Let the origin of our coordinate system be the left end of the original position of the beam as shown in the drawing. Assume there is no friction between the beam and floor. What is the location of the center of mass of the system? m Submit Help The medicine ball is throw to the left end of the beam (and caught). What is the location of the center of mass now? m Submit Help What is the new x-position of the person at the left end of the beam? (How far did the beam move when the ball was throw from person to person?) m Submit Help To return the medicine ball to the other person, both people walk to the center of the beam. At what x-position do they end up? m Submit Help

To give a 11−Kg child a ride, two teenagers pull on a 3.7−Kg sled with ropes, as indicated in the figure below. Both teenagers pull with a force of 55 N at an angle of 35∘ relative to the forward direction, which is the direction of motion. In addition, the snow exerts a retarding force on the sled that points opposite to the direction of motion and has a magnitude of 57 N. Calculate the acceleration of the sled and child.
