1. Homework Statement
hey guys, i am new in this forums and would love help with a question i have encountered with an assignment that i am doing.The question is :
At a crime scene, the forensic investigator notes that a 8.2g lead bullet that was stopped in a door frame apparently melted completely on impact. Assuming the bullet was fired at room temperature(20 degree celcius), what does the investigator calculate as the minimum muzzle velocity of the gun?
cheers
2. Homework Equations
equation i tried is 0.5mv^2=3/2 k T
k=boltzman constant
3. The Attempt at a Solution
i got a really really small answer for it so i doubt that is the correct solution to it. I read through that part in my textbook and don't seem to find any similar questions. Hope that someone is able to clarify and make me understand what i am suppose to do.I have a test coming up as well,so solutions and an explanation to this question would be very much appreciated.
Cheers
