I wasn't guessing I just mistook it for kg*m/s^2, and for the equation I know mass should be used but I have no idea of how to get it

Yeah your right It's Newton so its going to be 210kN

I really don't know what to tell you :D, except that my physics prof likes to make life hard.

210,000 J (jules) = 210 kJ (kiloJules) density is in kg/m^3 Velocity is in ms^-1

I hope the image quality is ok.

I can take the starting temp to be 25 C room temp. But still I am confused as to how to link the KE to the change in Temp

I have taken that the density of silver is 10.5 kg/m^3 and from the formula KE= (rho*V^2)/2 to get 210kJ, But the problem I am facing is that I need to find the Delta T of the bullet but I have no starting Temp.

Sorry I am new to this forum,, for the problem that is the full problem. There is no more added information its just that :/

Yeah It doesn't seem logical that's why I'm having a hard time with it.

Summary:: What is the temperature change of a bullet upon impact. I have this problem to solve but I'm kinda stuck, would apricate any feedback. We fire a silver bullet with a muzzle speed of 200 ms−1 into a sack of sand. What is the temperature change of the bullet, if 40 % of its kinetic...
