Critical problem for serious learning
The figure above shows a so-called double Atwood machine with masses $m_1 = 4.5 \text{ kg}$, $m_2 = 4.5 \text{ kg}$, and $m_3 = 4 \text{ kg}$. The strings and pulleys are massless and frictionless. The system is subject to the regular force of gravity ($g = 9.80665 \text{ m/s}^2$).
Determine the magnitude of the accelerations for $m_1$, $m_2$, and $m_3$.
(a) Magnitude of $a_1$ =
(b) Magnitude of $a_2$ =
(c) Magnitude of $a_3$ =
