A uniform object of mass \(M\) and radius \(R\) is released from rest at the top of a ramp inclined at an angle \(\theta\) to the horizontal. The object rolls without slipping as it moves down the ramp. The rotational inertia of the object is given by the expression \(I = cMR^2\), where \(c\) is a dimensionless constant. Which of the following expressions correctly represents the distance \(d\) the object travels along the ramp as a function of time \(t\)?
