A cord passing over a frictionless, massless pulley (Atwood's machine) has a $m_2 =$ 10-kg block tied to one end and a $m_1 =$ 12-kg block tied to the other. If at the end of 3 seconds the string is cut, find the distances moved by the masses $d_1$ and $d_2$ in the next 6 seconds.

The device shown here is called an Atwood's machine. m$_1$ and m$_2$ are suspended at the ends of a string of negligible mass passing over a friction-less pulley as shown here. What is the tension in the light cord that connects the two masses?

The system on the left shown here is called an Atwood's machine. m$_1$ and m$_2$ are suspended at the ends of a string of negligible mass passing over a friction-less pulley as shown here. The system on the right just has a hanging mass m. What should m be in terms of m$_1$ and m$_2$ so that the tension in the top string is the same in both cases? Assume that the two systems have equal downward acceleration (a').

The device shown here is called an Atwood's machine. m$_1$ and m$_2$ are suspended at the ends of a string of negligible mass passing over a friction-less pulley as shown here. How far will m$_1$ fall in time $t$ after the system is released?

The device shown here is called an Atwood's machine. m$_1$ and m$_2$ are suspended at the ends of a string of negligible mass passing over a friction-less pulley as shown here. What is the acceleration and the tension in the light cord that connects the two masses if m$_1$ = 12 kg and m$_2$ = 4 kg?
