MHT CET 2026 11th April Evening Shift | Center of Mass and Collision Question 6 | Physics

A mass M moving with velocity V along X-axis collides and sticks to another mass 2M which is moving along Y-axis with velocity 3V. The velocity of the combination, after the collision is

$V\hat{i} + 2V\hat{j}$

$\dfrac{V}{3}\hat{i} + 2V\hat{j}$

$V\hat{i} + 3V\hat{j}$

$2V\hat{i} + 4V\hat{j}$

A sphere of mass ' $m$ ', moving with velocity ' $3 u$ ' collides head-on with another identical sphere at rest. If ' $e$ ' is coefficient of restitution then what will be the ratio of velocity of the second sphere to that of first sphere after collision?

$\frac{1-\mathrm{e}}{1+\mathrm{e}}$

$\frac{1+\mathrm{e}}{1-\mathrm{e}}$

$\frac{e+1}{e-1}$

$\frac{e-1}{e+1}$
