A 10.0 kg cart and a 15 kg cart are locked together with a compressed spring between them. They are then released so that the spring pushes the two carts apart. The 10.0 kg cart is moving at 3.0 m/s afterward. How fast is the 15 kg cart moving

  1. Assuming we can ignore the mass and motion of the spring, then we need to conserve momentum

    10(3) = 15v

    A cart is launched on an air track with a certain speed from the force of a compressed spring. If you wanted to launch the cart at twice the speed, the spring should be compressed by? I say twice as much.

    Suppose that the graph of force vs. time for a very unusual spring has only straight lines. The cart hits the spring at t = 3.00 s, so force F = 0 up to that point. Then, after t = 3.00 s, the force increases linearly until it
