A cannon has a barrel 6.8 m long and fires a 1.2 kg projectile with a muzzle velocity of 88.3 m/s. What is the average force (in N) on the projectile?

You need to show some attempt before anyone at PF can help you.

Start by considering change in kinetic energy of the projectile.
 
F=687.96n
 
Yes that is correct.
