Calculate the acceleration

  1. Nov 13, 2006 #1
    I am doing an experiment where a cart is connected to a hooked hanger via pulley. The weight of the system is constant throughout the experiment, but weights are taken from the cart and connected to the hanger. We then record the time it takes the cart to travel a certain distance of time. I am able to calculate the acceleration. However, I am required to also calculate the force needed to accelerate the cart. Do I multiply the mass of the cart (with the weights on top included) by the acceleration or do I multiply the mass on the hooked hanger by the acc.? thanks

    F = ma

    mult the mass of the system by the acceleration...then you'll get the force
