Slope Problem

  1. Sep 24, 2009 #1
    A car traveling at 25 m/s runs out of gas while traveling up a 9.0 slope.
    How far will it coast before it starts to roll back down?
    How do you find the rate at witch gravity pulls the car down the slope? I dont understand how to find that

    Hi grizzly44! Welcome to PF! :smile:

    The car will have a constant acceleration …

    find that acceleration by using good ol' Newton's second law in the direction of the slope. :wink:

    Ok so i know how to do that one one dimensional kinematics but how do i apply that to a slope?

    A slope is one-dimensional. :wink:

    The only difficulty is finding the F in F = ma …

    it will be the total of the component along the slope of the gravity and the friction force.
