tell me how to solve this niggers.

"A lead bullet is fired with an airgun through a piece of wood. The speed of the bullet before it hits the piece of wood, is 500 m/s and after it hit it's speed is at 300 m/s. Assume that 40% of the loss in kinetic energy is transformed into heat energy in the bullet. Calcutate the rise in tempurature of the lead bullet.

The specific heat capacity of lead is 130J * kg^-1*K^-1 ."

Write any formulas you take use of in solving this.

Not really. I fucking hated middle school. I wouldn't want to go back for anything.

It seems extremely likely that there is an energy source that is possible to tap that will provide us with unlimited energy. Discuss.
