Train Collision and Newtons First Law A group of college students discusses the train collision case study. Use Newtons first law to decide which underlined statements are correct and which are false. Explain your answers. Shannon: This newspaper says that the people who got really hurt were either standing up or sitting in a forward-facing seat. Those people got thrown forward when the train stopped. Avi: Thats why there are seat belts in cars. If you get into a crash, the force can throw you through the windshield. Cameron: There is no force that throws you through the windshield. You fly through the windshield because you are already moving and it would take a force to stop you from going forward. Thats why theres a seat belt. Avi: That doesnt make sense. Because then you would need a force to stop you from flying through the windshield even when you just stop slowly at a red light. Cameron: Thats right, but when you slow down slowly, you dont need such a big force and the car seat can take care of it. Shannon: The seat? I dont think a seat can exert a force. It cant move on its own or hold you. Thats why the people who were sitting forward on the train were hurt. The people who were sitting backward had the back of the seat to block them.

Twenty people participate in a tug-of-war. The two teams of ten people are so evenly matched that neither team wins. After the game they notice that a car is stuck in the mud. They attach the tug-of-war rope to the bumper of the car, and all the people pull on the rope. The heavy car has just moved a couple of decimeters when the rope breaks. Why did the rope break in this situation when it did not break when the same twenty people pulled on it in a tug-of-war?
How are force and motion related?
The two barges shown here are coupled by a cable of negligible mass. The mass of the front barge is 2.00103kgand the mass of the rear barge is 3.00103kg . A tugboat pulls the front barge with a horizontal force of magnitude 20.0103N . and the frictional forces of the water on the front and rear barges are 8.00103Nand 10.0103N . respectively. Find the horizontal acceleration of the barges and the tension in the connecting cable.
In Section 2.4, we computed the force needed to accelerate a 1,000-kg car from 0 to 27 m/s in 10 s. Compute the force using the alternate form of Newton’s second law. The change in momentum is the car’s momentum when traveling 27 m/s minus its momentum when going 0 m/s.
-m rope is tied to a tree; the other end is tied to a car stuck in the mud. The motorist pulls sideways on the midpoint of the rope, displacing it a distance of 2 m. If he exerts a force of 80 N under these conditions, determine the force exerted on the car.
A car moves along a horizontal road. Draw a free- body diagram; be sure to include the friction of the road that opposes the forward motion of the car.
An athlete grips a light rope that passes over a low-friction pulley attached to tire ceiling of a gym. A sack of sand precisely equal in weight to the athlete is tied to the other end of the rope. Both the sand and the athlete are initially at rest. The athlete climbs the rope, sometimes speeding up and slowing down as he does so. What happens to the sack of sand? Explain.
