Constants Periodic Table (Figure 1)The car shown in the figure has mass m (this includes the mass of the wheels). The wheels have radius r, mass mw, and moment of inertia I = kmwr2. Assume that the axles apply the same torque T to all four wheels. For simplicity, also assume that the weight is distributed uniformly so that all the wheels experience the same normal reaction from the ground, and so the same frictional force. Part B Use Newton's laws to find an expression for the net external force acting on the car. Ignore air resistance.
