Two balls of masses ${m_1}$ and ${m_2}$ are separated from each other by a powder charge placed between them. The whole system is at rest on the ground. Suddenly the powder charge explodes and masses are pushed apart. The mass ${m_1}$ travels a distance ${s_1}$ and stops. If the coefficients of friction between the balls and ground are same, the mass ${m_2}$ stops after travelling the distance
  • A${s_2} = \frac{{{m_1}}}{{{m_2}}}{s_1}$
  • B${s_2} = \frac{{{m_2}}}{{{m_1}}}{s_1}$
  • C${s_2} = \frac{{m_1^2}}{{m_2^2}}{s_1}$
  • D${s_2} = \frac{{m_2^2}}{{m_1^2}}{s_1}$
