Mike and Tim are outside with a wagon. Tim weighs 311 Newtons (70lbs) and gets in the wagon and Mike, who weighs 50 Newtons (50lbs), pulls it. As Mike pulls it, he accelerates until reaching a constant velocity. After stopping, Mike and Tim switch places. Tim now pulls Mike in the wagon, accelerating from a stop to a constant velocity . Now, Tim may be bigger than Mike, but Mike has been working out and is just as strong as Tim, so the force that Tim uses to pull the wagon is the same force that Mike used. Both pull with the exact same amount of force. Who was riding in the wagon when it had the greatest acceleration during start up? Why? Use Newton’s second law to explain. Now Sara comes along, and she is the exact same size as Mike. However, she is even stronger than Mike! When she pulls Mike in the wagon, she pulls with a greater force than when Mike pulls her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton’s second law.
