A lab cart with a mass of 567 grams has an initial speed of 1.23 meters per second. While the cart rolls through a distance of 35.3 centimeters, a constant force of 4.78 newtons pushes the cart in the direction it's moving. At the same time, friction does -0.237 joules of work. What is the cart's final speed? Include units in your answer.
