Homework Help: Kinematics Question. Car's acceleration

  1. Sep 5, 2010 #1
    A van is traveling with uniform acceleration along a straight road. The road has marker posts every 100 m. When the car passes one post, it has a speed of 10 ms-1 and, when it passes the next one, its speed is 20 ms-1.

    What is the car’s acceleration?

    Per forum rules, please list the relevant equations and show an attempt at a solution, and someone will be glad to help. You should be familiar with the kinematic equations of motion for constant acceleration.
