Consider the system shown in the figure below and assume that: The wheel rolls without slipping on mass M2. 12.• The block M2is able to slide without friction on the

horizontal surface, There is an external torque T (t)is applied on the wheel that drives the whole system. \left(I-M_{2} r^{2}\right) \ddot{x}_{2}-K r^{2} x_{2}=r \tau \bigcirc\left(I+M_{2} r^{2}\right) \ddot{x}_{2}+K r^{2} x_{2}=r \tau \left(I+M_{2} r^{2}\right) \ddot{x}_{2}-K r^{2} x_{2}=r \tau \left(I+M_{2} r^{2}\right) \ddot{x}_{2}+K r^{2} x_{2}=-r \tau
