Question

A 2.5 kg cart is rolling across a frictionless, horizontal track toward a 2 kg cart that is held initially at rest. The carts are loaded with strong magnets that cause them to attract one another. Thus, the speed of each cart increases. At a certain instant before the carts collide, the first cart’s velocity is +4.4 m/s, and the second cart’s velocity is -2.1 m/s. What is the total momentum of the system of the two carts at this instant?

Step 1

The momentum of an object is given by the formula: momentum = mass x velocity. For the first cart: momentum = 2.5 kg x 4.4 m/s = 11 kg*m/s For the second cart: momentum = 2 kg x (-2.1 m/s) = -4.2 kg*m/s Show more…
