F*x = 1/2*m*v^2
where F is the average force, x is the distance over which the bullet is accelerated, v is the speed, m is the mass of the bullet
F*0.432 = 1/2*22*907^2
A 22 g bullet is accelerated in a rifle barrel 43.2 cm long to a speed of 907 m/s.
Use the work-energy theorem to find the average force exerted on the bullet while it is being accelerated.
