TS EAMCET · Physics · Center of Mass Momentum and Collision
A moving body with a mass \(m_1\) and velocity \(u\) strikes a stationary body of mass \(m_2\). The masses \(m_1\) and \(m_2\) should be in the ratio \(\frac{m_1}{m_2}\), so as to decrease the velocity of the first body to \(\frac{2 u}{3}\) and giving a velocity of \(v\) to \(m_2\) assuming a perfectly elastic impact. Then, the ratio \(\frac{m_1}{m_2}\) is
- A 5
- B 1/5
