Below is a table of all the variables we used: 5 m/s like we predicted and we were pretty accurate. After getting the x value, we compressed each spring the given amount and using PASCO Capstone we preformed a final test to see if the carts would come off at around. 5 m/s for both and plugged all the values into the formula and solved for x for both carts. We were given the k constant for each cart, and then we picked a velocity we wanted the carts to come off at for consistency purposes. We set up 2 equations for each cart, and then weighed them both and converted their weights into kg. We were looking for the x value in the elastic energy formula which represents the amount the spring needs to be compressed and we had the other values to plug into the formula to solve. Because the energy for the system which consists of the cart, the spring, earth, and track, starts off all in elastic energy and finishes all in kinetic energy, our conservation of energy equation is Eel=Ek or 1/2kx^2=1/2mv^2. We did not have to take much data for this experiment as much of it was plug and chug after we figured out the equation.
