How Fast Must a Bullet Travel to Heat Water by 1.3 Degrees Celsius?

[shakejuhn]

Homework Statement

How fast would a 4.54g bullet have to be traveling so that it increased the temperature of 1.00 L of water by 1.30oC if it gave all of its kinetic energy to the water?

Homework Equations

i don't know what equation to use i have two of them but its seems they don't apply to this problem

mgh-.5MVf^2=q

q=cM(Tf-Ti)
q=C(Tf-Ti)

The Attempt at a Solution

please point me in the correct direction so i can attempt the problem

What unit of energy does it take to raise water by 1C? How do you convert from that into MKS units of energy? What is the kinetic energy of the bullet (your equation above is not correct -- close, but not right)?

You have only one eqn, viz., that of energy conservation. (Use CGS and then convert to SI, as had been advised.)
