Homework Help: Simple Physics Problem - Acceleration Formula

  1. Oct 15, 2009 #1
    1. A cart is rolling down an incline for 6 seconds. If the cart has a begginning speed of 2 meters per second and the incline is 5 meters long, what is the carts acceleration?

    2. a= v1 - v2 / t

    3. I'm just learning the acceleration formula in my physics class. I left my science book at school, thinking I would not need it because the worksheet we were given looked simple. But teacher threw in this problem and I'm not sure what to do about the incline. I need my final velocity to figure out the problem, but I'm sure what I do with the 5 meter long incline to get the final velocity.

    try to use [tex] x = x_0 + v_0 t + (1/2) a t^2 [/tex]

    I'm not sure what all the variables in that formula are. I just need someone to explain how to get the final velocity.

    x is final position, x_0 is initial position, v_0 is initial velocity, t is time, a = acceleration.
