1. The problem statement, all variables and given/known data A 3 m long canon fires a 14.0 kg projectile with a velocity of 630 m/s [F]. Calculate. A) The kinetic energy of the projectile as it leaves the canon barrel. B) The average force acting on the projectile in the barrel. 3. The attempt at a solution A) Ek=1/2*14kg*630m/s Ek=2.8*10^6j B)2.8*10^6j=Fnet*3m Fnet=2.8*10^6N/3m Fnet=9.3*10^5N Is that Right?
