A 20 gram bullet strikes a 15 kg mass attached to a spring. The mass aslides and compresses the spring by 12 cm. Calculate the velocity of the bullet initially.

Bullet............................Mass..........Spring

...D.............................I--------I

..................................I...........I~~~~~~~~|

.........................._____I_______I___________|

2. Relevant equations

3. The attempt at a solution

i was thinking to use (1/2) x (K) x (x squared) = (1/2) x (m) x (v squared)

then i was told to solve for p (momentum) (??) after using the above formula
