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.

    The wheels of a midsize car exert a force of 2100 N backward on the road to accelerate the car in the forward direction. If the force of friction including air resistance is 250 N and the acceleration of the car is 1.80 m/s, what is the mass of the car plus its occupants? Explicitly show how you follow the steps in the Problem-Solving Strategy for Newton’s laws of motion. For this situation, draw a free-body diagram and write the net force equation.

    It takes the elevator in a skyscraper 5.0 s to reach its cruising speed of 12 m/s. A 65 kg passenger gets aboard on the ground floor. Part A What is the passenger's weight before the elevator starts moving? Express your answer with the appropriate units. Part B What is the passenger's weight while the elevator is speeding up? Express your answer with the appropriate units. Part C What is the passenger's weight after the elevator reaches its cruising speed? Express your answer with the appropriate units.
