... Translating this to the boxes above gives ax = 1.4 m/s , ay = 0 for m1, and ax = 0, ay = -1.4 m/s2 for m2. We note that the tension is less than the weight of m2, m2g=49 N. This agrees with the drawing, where the weight overcomes the tension and makes m2 accelerate downwards. (b) Suppose m1 = 0. The ...
