Three shopping carts are initially stationary on a slope, the friction in the wheels allowing them to stay still. A shopper accidentally strikes Cart A, giving it a downward slope speed of 1.1 m/s. After traveling 2 m, it strikes cart B and both then roll together at the same speed, striking Cart C after traveling another 2 m. How fast are the carts moving after Cart C has been struck?
