(adsbygoogle = window.adsbygoogle || []).push({}); The maximum deceleration of a car....

1. The problem statement, all variables and given/known data

The maximum deceleration of a car on a dry road is about 8.0 m/s^2

3. The attempt at a solution

A)

If two cars are moving head-on toward each other at 88 km/h (55 mi/h), and their drivers apply their brakes when they are 85 m apart, will they collide?

Answer: No

B)

How far apart will they be when they stop?

Answer: 10m

C) HELP Drawing the graph and points

On the same graph, plot distance versus time for both cars.

Assume x = 0 is the midpoint between the cars and t = 0 when the brakes are applied. Label the position versus time plot of the car with the positive velocity as x_1(t).
