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)
