A force F=157 N pushes a box forward on a level surface, while a frictional force f - 42 N opposes the motion. The mass of the box is m=5 kg, and the box starts from a velocity of +2 m/s. If the box travels a distance of 5 m along the +x axis, what will be its speed v at the end of this distance? Express your answer in meters per second (m/s). 14- 1L
