A1000 kilogram empty cart moving with a speed of 6.0 meters per second is about to collide with a stationary loaded cart having a total mass of 5000. kilograms. after the collision, the carts lock and move together. [assume friction is negligible.]
a) calculate the speed of the combined carts after the collision. [show all work, including the equation and substitution with units.]
b) calculate the kinetic energy of the combined carts after the collision. [show all work, including the equation and substitution with units.]
c) how does the kinetic energy of the combined carts after the collision compare to the kinetic energy of the carts before the collision?
