Newton's second law:
ΣF = ma
T2 - M2g = 0
T2 = M2g
Two blocks with masses M1 and M2 hang one under the other. For this problem take the positive direction to be upward, and use g for the magnitude of the acceleration due to gravity
1. Find T2, the tension in the lower rope
2. Find T1, the tension in the upper rope
For question 3 and 4 the blocks are now acceleration upward due to the tension in the strings with acceleration of magnitude a.
3. Find T2, the tension in the lower rope
4. Find T1, the tension in the upper rope
Express answers in terms of M1, M2 and g
