A massive ball moving with speed v collides with a tiny ball by negligible mass. The collision is elastic. Find the speed with which the second tiny ball will move.

Text Solution

Verified by Experts

`V_2 = (2(m_1u_1))/((m_1 + m_2))`
Since `m_1 > > m_2, (m_1 + m_2) = m_1`
or `v_2 = (2m_1v)/(m_1) = 2v`
`:.` Sneed of second tiny ball = 2v.
