Hocky puck vel/displacement/acc

  1. Oct 1, 2007 #1
    1. By pumping air up through thousands of tiny holes we can make a horizontal air table that will support several pucks so that they can move around on cushions of air with very little friction. Suppose that one such puck initially at rest, having a mass of 0.250 kg, is pushed along by a 1.00 N force for 2.00 s. Determine its acceleration and the final velocity at the end of 2.00 s. What will be the displacement?

    2. Well, of all the equations that I thought I should use, I thought it would be Acceleration=(Velocity final-Velocity initial)/(time)

    3. I've made several attempts at a solution but I'm not sure if I'm using the right equation, someone mind pushing me in the right path?

    Never mind. I figured out that f=ma and I know the force and the mass. No biggy :)
    The rest will be easy to figure out, thanks :)
    Though, it would be (1 kg m/s^2)/ (.250 kg) = 4 m/s^2, correct?
