1. The problem statement, all variables and given/known data two 3.5g bullets are fired with speeds of 42.4 m/s and the 2nd one with 69.6 m/s what is the kinetic energy of the first bullet? the second one? 2. Relevant equations EK=(1/2)mv^2 3. The attempt at a solution EK=(1/2)3.6*42.4^2 = 3235.968 it is wrong.. why?
