Now that we’ve seen that the change in the momentum of the cart-disk system is a decrease of just a few percent, let’s compare the kinetic energy before and after the collision as well. Calculate the percent change in kinetic energy of the cart-disk system resulting from the collision. Express your answer as a positive or negative percentage to three significant figures, to indicate either an increase or decrease in kinetic energy.
