A sphere of mass m moving with a constant velocity u hits another stationary sphere of same mass. If e is the coefficient of restitution, then ratio of velocities of the two spheres \(\frac{\mathrm{v}_{1}}{\mathrm{v}_{2}}\) after collision will be :
- \(\frac{1-\mathrm{e}}{1+\mathrm{e}}\)
- \(\frac{1+\mathrm{e}}{1-\mathrm{e}}\)
- \(\frac{e+1}{e-1}\)
- \(\frac{e-1}{e+1}\)
Answer
(B) 1+ e 1- e
