A bullet of mass m traveling with an initial velocity v strikes a stationary wooden block of mass M, which is suspended. After the collision, the block rises to a height h. Determine the initial velocity v of the bullet.

1. A bullet of mass m, moving with an initial velocity v, strikes a stationary wooden block of mass M, which is suspended. After the collision, the block rises to a height h. What was the initial velocity v of the bullet?

A) \( v = \sqrt{2gh} \)
B) \( v = \frac{(M + m)}{m} \sqrt{2gh} \)
C) \( v = \frac{m}{(M + m)} \sqrt{2gh} \)
D) \( v = \frac{m}{M} \sqrt{2gh} \)
