# A block with mass \( m \) slides at speed \( v_0 \) on a smooth surface and hits a stationary block with mass \( M \). They stick together and move at speed \( \frac{v_0}{3} \). Find \( M \) in terms of \( m \).

A block with mass \( m \) slides at speed \( v_0 \) on a smooth surface and hits a stationary block with mass \( M \). They stick together and move at speed \( \frac{v_0}{3} \). Find \( M \) in terms of \( m \).

- **A.** \(\frac{m}{3}\)
- **B.** \(\frac{m}{2}\)
- **C.** \( m \)
- **D.** \(2m\)
- **E.** \(3m\)
