1. The problem statement, all variables and given/known data A 16 g bullet is accelerated in a rifle barrel 72.3 cm long to a speed of 1010 m/s. Use the work-energy theorem to find the average force exerted on the bullet while it is being accelerated. Answer in units of N. 2. Relevant equations W=changeKE 3. The attempt at a solution Fx=(mvf^2)/2-(mvi^2)/2 F=((16*1010^2)/2*.723 F=1.1287e7 Did I do this correctly?
