Question

A $m_1$ = 1.95-kg aluminum block and a $m_2$ = 7.10-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 $\theta$ = 32.0°) as shown in the figure. (For aluminum on steel, $\mu_s$ = 0.61 and $\mu_k$ = 0.47. For copper on steel, $\mu_s$ = 0.53 and $\mu_k$ = 0.36.) Aluminum Copper Steel (a) the acceleration of the two blocks Enter a number. differs from the correct answer by more than 100%. m/s$^2$ (b) the tension in the string Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. N
