The two masses $m_1=3kg$ and $m_2$ are connected by a massless string passing through a massless pulley as shown in the figure below. If the system is released from rest when $m_1$ is on the ground and $m_2$ is $h=4,5m$ above the ground, $m_2$ hits the ground with a speed of $v=2,6\frac{m}{s}.$ Determine the mass of $m_2.$ Take $g=9\mathrm{.}8\frac{m}{s^2}$ and express your answer in units of kg using one decimal place.
