$- 0.1 m/.$  અને  $0.8 m/s$

Vedclass · Answer

${v_1}\,\, = \,\,\left( {\frac{{{m_1}\,\, - \,\,e{m_2}}}{{{m_1}\,\, + \;\,{m_2}}}} ight)\,\,{u_1}\,\,\, \Rightarrow \,\,{v_1}\,\, = \,\,\frac{{\left( {m\,\, - \,\,2m\,\,\left( {0.6} ight)} ight)}}{{3m}}\,\,{u_1}\,\, = \,\,\left( {\frac{{1\,\, - \,1.2}}{3}} ight)\,\,{u_1}\,$

$ = \,\, - \,\,\frac{{0.2}}{3}\,\, 	imes \,\,1.5\,\, = \,\, - 0.1\,\,m/s$

તેમજ $\,e\, = \,\,\frac{{{v_2}\,\, - \,\,{v_1}}}{{{u_1}\,\, - \,{u_2}}}\,\, \Rightarrow \,\,0.6\,\, = \,\,\frac{{{v_2}\,\, + \;\,0.1}}{{1.5\,\, - \,\,0}}$

$ \Rightarrow \,\,{v_2}\,\, = \,\,0.6\,\,\, 	imes \,\,1.5\,\, - \,\,0.1\,\, = \,\,0.9\,\, - \,0.1\,\, = \,\,0.8\,\,m/s$
