After completing this simulation, the student will be able to Calculate final velocity in an elastic collision Calculate final velocity in an inelastic collision Compare and contrast conservation of momentum and energy in collisions Describe elastic and inelastic collisions in terms of coefficient of restitution. User Interface and Simulation Features This simulation consists of carts colliding in one-dimensional motion on a frictionless air track. You can vary the coefficient of restitution for these collisions A value of 0 represents a completely inelastic collision and a value of 1 0 represents a completely elastic collision The mass and velocity of each cart can be changed. You can also drag each cart to a desired starting position before starting the simulation. You can choose to show the location of the center of mass of the two-cart system. The simulation continues to run after the carts reach the ends of the track so that you can record or print the final momentum and velocity values When you are done, remember to stop the simulation using the icon on the left of the screen In each case when you start a simulation for the following questions reset the values using the icon in the control panel at the left side of the screen Each question assumes that you have done this Then set only the values indicated in the question a introductory Level From the default values, calculate the initial momentum of each cart Be careful to use the correct sign, since momentum is a vector quantity What are these values? Algebraically add the two values Run the simulation What is the final total momentum value indicated by the simulation? Does it differ from the value you calculated? Accept the default values Change the velocity of cart B to -6.0 m/s. Calculate the final velocity of this collision Run toe simulation Does the value for final velocity in the simulation agree with your value
