Question

A \(m_{1}=1.10-\mathrm{kg}\) aluminum block and a \(m_{2}=6.15-\mathrm{kg}\) copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle \(\theta=30.5^{\circ}\) ) as shown in the figure. (For aluminum on steel, \(\mu_{s}=0.61\) and \(\mu_{k}=0.47\). For copper on steel, \(\mu_{\mathrm{s}}=0.53\) and \(\mu_{k}=0.36 .\).)

(a) the acceleration of the two blocks

(b) the tension in the string
