content/public/007.Momentum and Impulse/Conservation of Momentum/Coin in a Funnel/MarbleinaFunnel.png

A coin is inserted into a donation machine. It leaves the entry track with a velocity of \({{params.vo}}\) m/s horizontally in a funnel, making an angle \(\alpha\). Determine the angle \(\theta\) which its velocity makes with the horizontal as the coin passes bottom of the funnel. Assume the coin always remains spinning on its thin edge. \(r = {{params.r1}}\) m, The radius of the opening at the bottom is \(r2 = {{params.r2}}\) m, \(\alpha= {{}}^\circ\)
