Two blocks with mass M1 = 30 kg and m2 = 5 kg are connected together with a massless, inextensible rope. You pull on a second identical rope attached to the m2 mass and accelerate both masses upward with an acceleration of 3 m/s2.

a. What are the magnitudes of the tensions T1 and T2?

b. If the maximum tension this type of rope can withstand without breaking is 700 N, and m2 is unchanged, what would be the maximum value of M1 that would allow you to lift both masses upward with an acceleration of 3 m/s2?
