1. The problem statement, all variables and given/known data The graph below shows the net force applied to a 2.5 kg body, initially at rest but free to move along a straight line on a horizontal frictionless surface. The force acts along the same straight line. After the body has moved 3 m, what is it's kinetic energy? 2. Relevant equations KE=1/2mv^2 3. The attempt at a solution I just don't understand how to figure out the velocity of the body given force versus distance. Can someone explain this?
