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 the masses are pushed apart. The mass $m_1$ travels a distance $s_1$ and stops. If the coefficients of friction between the balls and the ground are the 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$s_2 = \frac{m_2^2}{m_1^2} s_1$

Their masses follow the sequence $m, \frac{m}{2}, \frac{m}{6}, \ldots, \frac{m}{n!}, \ldots$ and they are further connected to a mass $m$ that hangs over a massless pulley. The acceleration of the hanging mass is
