A body of mass 2 kg is initially at rest on a horizontal frictionless plane. It is then pulled 4 meters by a horizontal force of magnitude 25N. a). Use the work-energy relation to find its final speed. b). If supposed that the body has an initial velocity of 10m/s and is then pulled 4 meters by a force of magnitude 25N in the direction of the initial velocity, what is its final velocity?
