An object of mass \(m\) is initially at rest on a frictionless horizontal surface at time \(t = 0\). A single horizontal net force \(F\) directed along the positive \(x\)-axis is applied to the object. The graph of the force \(F\) as a function of time \(t\) is shown. Which of the following graphs best represents the momentum \(p\) of the object as a function of time \(t\)?
