Applying Newton’s second law, we obtain 11 1 22 2 sin Tm g m a mg T ma θ −= Adding the two equations allows us to solve for the acceleration: 21 mm ag θθ §· = ¨¸ + ©¹ With 1 30 and 2 60 , we have a = 0.45 m/s 2 . This value is plugged back into either of the two equations to yield the tension T = 16 N. 99. The + x axis is “uphill” for
