Problem

In an ideal Atwood machine, an unknown mass

m

is suspended on one side and a

4.0\,\text{kg}

mass on the other side. When released, the unknown mass is observed to accelerate upward at

0.60\,\text{m\,s}^{-2}

. Calculate the value of

m

. a)

4.5\,\text{kg}

3.2\,\text{kg}

3.5\,\text{kg}
