The system is released from rest in the configuration shown at time $t=0.$ Determine the time $t$ when the block of mass $m_1$ contacts the lower stop of the body of mass $m_2.$ Also, determine the corresponding distance $s_2$ traveled by $m_2.$ Use the values $m_1=0\mathrm{.}9kg,m_2=3\mathrm{.}7kg,{}_s=0\mathrm{.}19,{}_k=0\mathrm{.}15,$ and $d=0\mathrm{.}59m.$
