Chapter 1: Q8DQ (page 123)

Some people say that the 鈥渇orce of inertia鈥� (or 鈥渇orce of momentum鈥�) throws the passengers forward when a car brakes sharply. What is wrong with this explanation?

Short Answer

Expert verified

The breaks should be applied suddenly and not sharply.

Step by step solution

01

Inertia

Inertia is a property of a body that makes it resist any change in its state, whether rest or uniform motion.

02

Comment on the given explanation

The force of inertia throws a passenger in a moving car when breaks are applied suddenly, not sharply. This was the error in explanation.

So, there should be the sudden application of breaks not the sharp application of breaks.

Starting from the front door of a ranch house, you walk 60.0 m due east to a windmill, turn around, and then slowly walk 40.0 m west to a bench, where you sit and watch the sunrise. It takes you 28.0 s to walk from the house to the windmill and then 36.0 s to walk from the windmill to the bench. For the entire trip from the front door to the bench, what are your (a) average velocity and (b) average speed?

In describing the size of a large ship, one uses such expressions as 鈥渋t displaces 20,000 tons.鈥� What does this mean? Can the weight of the ship be obtained from this information?
