A mass m is at rest on a horizontal frictionless surface at t=0. Then a constant force F0 acts on it for a time t0. Suddenly the force doubles to 2F0 and remains constant until t=2t0.   Part A Determine the total distance traveled fromt=0 to t=2t0. Express your answer in terms of the variables m, F0, t0, and appropriate constants.
