Chapter 5, Problem 56EAP

If a car stops suddenly, you feel “thrown forward.” We’d like to understand what happens to the passengers as a car stops.

Imagine yourself sitting on a very slippery bench inside a car. This bench has no fiction, no seat back, and there’s nothing for you to hold onto.

  1. Draw a picture and identify all of the force acting on you as the car travels at a perfectly steady speed on level ground.

  • Draw your free-body diagram. Is there a net force on you? If so, in which direction?
  • Repeat parts a and b with the car slowing down.
  • Describe what happens to you as the car slows down
  • Use Newton’s laws to explain why you seem to be “thrown forward” as the car stops. Is there really a force pushing you forward?
  • Suppose now that the bench is not slippery. As the car slows down. You stay on the bench and don’t slide off. What force is responsible for your deceleration? In which direction does this force point? Include a free-body diagram as part of your answer.

    EXPLANATION MUST BE TYPED - CANNOT BE HAND-WRITTEN On vacation, your 1400-kg car pulls a 560-kg trailer away from a stoplight with an acceleration of 1.85 m/s2. (a) What is the net force exerted on the trailer? (b) What force does the trailer exert on the car? (c) What is the net force acting on the car?
    A student’s backpack, full of textbooks, is hung from a spring scale attached to the ceiling of an elevator. When the elevator is accelerating downward at 3.8 m/s2 , the scale reads 60 N. (a) What is the mass of the backpack? (b) What does the scale read if the elevator moves upward while speeding up at a rate 3.8 m/s2 ? (c) What does the scale read if the elevator moves upward at constant velocity? (d) If the elevator had no brakes and the cable supporting it were to break loose so that the elevator could fall freely, what would the spring scale read?
    hree blocks are at rest on a smooth, horizontal table. You push on block A (m = 1.50 kg) to the right with a horizontal force of F push. As a result, block A pushes on block B (m = 2.50 kg), block B pushes on block C (m = 1.20 kg), and the system of blocks moves to the right with an acceleration of 1.12 m/s2. What is the magnitude of the force that block B exerts on block C?
