Thesis: How does the load affect the speed of the car at a constant rate?  

Device Description: We are designing a two car track system ran by 2 motors connected to each car which is pulled by a simple string and pulley system. Car one is the control of the system, which mean there is no load that could affect its performance. On the other hand the second car has an added load on the back. We are going to measure the change of weight of the load, the time it takes to finish the track.
