Problem

Two masses

m_1=2\,\text{kg}

and

m_2=4\,\text{kg}

are connected by a light string over a frictionless pulley. Calculate the magnitude of acceleration of the system (take

g=9.8\,\text{m s}^{-2}

). a)

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

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

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

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