A block of mass \(M\) moves to the right along a horizontal, frictionless surface with an initial speed \(v_0\) at time \(t = 0\). Starting at \(t = 0\), a time-dependent net horizontal force \(F(t) = C t^2\) is applied to the block in the direction of motion, where \(C\) is a positive constant. Which of the following integral equations correctly relates the speed \(v(t)\) of the block at a later time \(t\) to the force acting on it?
