An object of mass m is initially at rest. After a force of magnitude F acts on it for a time T, the object has a speed v. Suppose themass of the object is doubled, and the magnitude of the force acting on it is quadrupled. In terms of T, how much time does it takefor the object to accelerate from rest to a speed v now?
