$2.(5)$ A belt is fed over and around the light pulleys, which can freely spin about their fixed centers. If the speed $\backslash ($ v $\backslash )$ of the belt is constant and if the ratio of the magnitudes of the acceleration of points $\backslash ($ A $\backslash )$ and $\backslash ($ B $\backslash )$ is $\backslash (2/3\backslash ),$ determine the radius $\backslash ($ r $\backslash )$ of the larger pulley. The radius of the smaller pulley is $3$ cm $,$ as indicated. Can you please show and explain the steps clearly. Thanks in advance!!
