Concept explainers
Driving down the road, you hit the brakes suddenly. As a result, your body moves toward the front of the car. Explain, using Newton’s laws.
Answer to Problem 1CQ
Explanation of Solution
Inertia is the property of any object to resist the change its state of motion or state.
The Newton’s first law of motion states that an object remains in its state of rest or motion until or unless a external force applied on it. This is also known as the law of inertia.
When the brakes of the car apply suddenly then the body of person wants to remain in the state of motion due to the inertia. Thus the person moves toward the front of the car.
Conclusion:
Therefore, the body of a person moves toward the front of the car when the brakes apply suddenly is due to the inertia of motion.

- A block of mass m1= 10 kg is on a frictionless table to the left of a second block of mass m2 = 24 kg, attached by a horizontal string (Figure WU4.13). If a horizontal force of 120 N is exerted on the block m2in the positive x-direction, (a) use the system approach to find the acceleration of the two blocks.

(a) A single force acts on the object. (b) No forces act on the object. (c) Forces act on the object, but the forces cancel.arrow_forwardA 1 00-kg car is pulling a 300-kg trailer. Together, the car and trailer move forward with an acceleration of 2.15 m/s2. Ignore any force of air drag on the car and all friction forces on the trailer.

- In Example 4.5, we pushed on two blocks on a table. Suppose three blocks are in contact with one another on a frictionless, horizontal surface as shown in Figure P4.49. A horizontal force F is applied to m1. Take m1 = 2.00 kg, m2 = 3.00 kg, m3 = 4.00 kg, and F = 18.0 N. (a) Draw a separate free-body diagram for each block.

(e) You are working on a construction project. A coworker is nailing up plasterboard on one side of a light partition, and you are on the opposite side, providing backing by leaning against the wall with your back pushing on it. Every hammer blow makes your back sting. The supervisor helps you put a heavy block of wood between the wall and your back.
