An elevator car has two equal masses attached to the ceiling as shown. (Assume \( m=4.15 \mathrm{~kg} \).) (a) The cevater ascends with an acreleration of magnitude \( 1.40 \mathrm{~m} / \mathrm{s}^{2} \). What are the tensions in the two strings? (Enter your answers in N.) \[ \begin{array}{ll} T_{1}= & \mathrm{N} \\ T_{2}= & \mathrm{N} \end{array} \] (b) The maximum tensicn the strings can withstand is \( 99.4 \mathrm{~N} \). What is the maximum screleration of the elevator so that a string decs not break? (Enter the megnitude in m/s \( { }^{2} \).) \( m / s^{2} \)
