## Homework Statement

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 the mass of the object is doubled, and the magnitude of the force acting on it is quadrupled.

In terms of T, how long does it take for the object to accelerate from rest to a speed v now?
