Two masses are joined together by a massless, inextensible string. A vertical force of 30N applied to the upper mass gives the system a constant upward acceleration of $3.2 m / s^{2}$ . If the tension in the connecting string is 18N, what is the lower mass?

Options:

Answer:

Solution:

$18 - m_{2} g = m_{2} \times 3.2$

$18 = m_{2} (3.2 + 9.8)$

$18 = m_{2} (13)$

$m_{2} = \frac{18}{13} kg$
