A uniform solid sphere, a uniform solid disc and a thin ring, all of the same radius, are released from rest side by side at the top of a rough incline at $37^\circ$. Each has its axis horizontal and across the incline. The coefficient of friction between each body and the incline is $0.10$. Take $g = 10\ \text{m/s}^2$, $\sin 37^\circ = 0.6$ and $\cos 37^\circ = 0.8$. Which of the following statements are correct?
