## Homework Statement

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

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

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).

## Homework Equations

## The Attempt at a Solution

a. no they will not collide, they will be 10 m apart when they stop.

b. i think...

(0,-42.5) and (3,-5) for x_1(t)

and (0,42.5) and (3,5) for x_2(t)
