Consider two masses m1 and m2 are connected through a pully. Mass 'm2' starts from rest at height 'h' and falls down. With what speed it hits the ground?
(Assume no friction and massless strings & pulleys)
1
\(\sqrt {\left( {\frac{{{m_2}}}{{{m_1}\, + \,{m_2}}}} \right)\,gh} \)
2
\(\sqrt {2\,gh} \)
3
\(\sqrt {\left( {\frac{{{m_2}}}{{{m_1}\, + \,{m_2}}}} \right)\,2gh} \)
4
\(\sqrt {\left( {\frac{{{m_1}}}{{{m_1}\, + \,{m_2}}}} \right)\,2gh} \)
