A 15.4g bullet traveling at 270 m/s is fired into a 0.488kg wooden block anchored to a 100 N/m spring. How far is the spring compressed?
x_{compressed} =

If the speed of the bullet is not known but it is observed that the spring is compressed 43.9 cm, what was the speed of the bullet?
v_{bullet} =
