A 12.5 g bullet is shot into a ballistic pendulum that has a mass of 2.37 kg. The pendulum rises a distance of 9.55 cm above its resting position. What was the speed of that bullet?(adsbygoogle = window.adsbygoogle || []).push({});

m(bullet) = 0.0125 kg

m(pendulum) = 2.37 kg

h = 0.0955 m

I know that I'm supposed to use conservation of energy:

P(i)=P(f)

m(1)v(i)=(m(1)+m(2))v(f)

Unfortunately this equation does not take into account how high the pendulum swung, which is obviously an important factor.
