Physics - W.E.P. Question with Solution | TestHub

Kinetic energy $\mathrm{K}=\frac{{\mathrm{p}}^2}{2\mathrm{m}}$ Two masses are given as- ${\mathrm{m}}_1=1\mathrm{gm}$ and ${\mathrm{m}}_2=4\mathrm{gm}$ But ${\mathrm{K}}_1={\mathrm{K}}_2$ $\therefore \frac{{\mathrm{p}}_1^2}{2{\mathrm{m}}_1}=\frac{{\mathrm{P}}_2^2}{2{\mathrm{m}}_2}$ Or $\frac{{\mathrm{P}}_1^2}{2(1)}=\frac{{\mathrm{P}}_2^2}{2(4)}$ $⟹{\mathrm{P}}_1:{\mathrm{P}}_2=1:2$
