5. A uniform ball, of mass \(M = 5.00\) kg and radius \(R\), rolls smoothly from rest down a ramp at angle \(\theta = 30.0°\). The ball descends a vertical height \(h = 1.20\) m to reach the bottom of the ramp. The speed of the ball at the bottom is      (5)      m/s.

9. An air-filled parallel plate capacitor is connected to a battery of voltage \(V_0\). There is charge \(Q_0\) on each plate, energy \(U_0\) stored between the plates and an electric field of \(E_0\) between the plates. The capacitor remains connected to the battery and a dielectric material with a dielectric constant of \(K\) is then placed between the plates of the capacitor. What are the new values of \(V\), \(Q\), \(U\), and \(E\)? (10)
