College Physics (4th Edition)

The correct answer is: (b) $2.69~kg$
The correct answer is: (b) $2.69~kg$ Let $m$ be the mass of the object. Let the tension in the string be 35.0 N. We can find the maximum possible mass $m$: $\sum F = ma$ $T-mg = ma$ $T = m~(g+a)$ $m = \frac{T}{g+a}$ $m = \frac{35.0~N}{9.80~m/s^2+3.20~m/s^2}$ $m = 2.69~kg$
