Homework Statement
2. A 0.30 kg bullet is fired from a gun with a velocity of 410 m/s. The bullet then becomes embedded into a piece of wood with mass 5.5 kg hanging as a pendulum at rest. To what height will the piece of wood swing?
m1=.3kg
v1=410m/s
m2=5.5kg
v2=0
Homework Equations
m1v1 + m2v2 = m1(v1’+ v2’)
The Attempt at a Solution
i plugged in the variables (.3*410+5.5*0=.3(v1'+v2')), but it comes out to 410. I know that in a perfect inelastic equation all energy should transfer, but how can i use this to calculate the height the pendulum will reach?
