I have noticed just in the past couple of years that I get a red splotchy rash on my neck when I drink beer. I thought it might be an allergic reaction, but it doesn't happen all of the time when I drink beer. I have tried switching to a different kind of beer, but I still have random outbreaks of this rash. Answer.
So, if two objects have the same energy $E_k$, they only have the same momentum if they also have the same mass. Since the bull has a much larger mass than the bullet, it must therefore have a much larger momentum than the bullet to arrive at the same kinetic energy. Force is change of momentum with time, $F = \dot p$.
To determine the mass, we'll have to divide both sides by the product c*delta T. m = Q/c*Delta T. The requested formulas are for the change of temperature, the specific heat and the mass are: Delta T = Q/mc; c = Q/m*Delta T; m = Q/c*Delta T.
