A ball of mass (m1) impinges directly on a stationary ball of mass (m2). If the coefficient of restitution between them is (e) then the fraction of the total kinetic energy dissipated by the impact is :
1
\(\rm \frac{m_1(1-e^2)}{m_1 + m_2}\)
2
\(\rm \frac{m_2(1-e^2)}{m_1 + m_2}\)
3
\(\rm \frac{m_1(1-e)^2}{m_1 + m_2}\)
4
\(\rm \frac{m_2(1-e)^2}{m_1 + m_2}\)
