Dynamics Cart w/different masses - spring launcher

F=m*a

Use 2 dynamics carts on 2 different tracks, side by side. Attach a spring launcher to each track. You can keep the same or vary the mass of each cart and also vary the strength of each launcher. Set them up together, launch simultaneous, and let them race for comparison, based on their mass or force.
