Energy in collisions Statement of the problem: In the experiment, we used a track and 2 carts. One cart is given an initial velocity towards a stationary cart. There are pads at the end of each cart, which allow the carts to stick together after the collision. The problem was to determine the energy efficiencies over a range of initial velocities. The video analysis equipment is available to determine the velocities of the carts. We made 4 movies with the video equipment provided, each one with a different initial velocity of the moving cart. These movies were analyzed with LabVIEW to study the dependence of the initial velocity on the acceleration. Prediction Our group predicted that the efficiency of collision will be the same in each one of the experiments. We neglected the force of friction because the surface of the block is very smooth. The velocity after the collision is constant until the end of the experiment due to Newton’s 1 st law. 2
