A 22 g bullet is fired from a rifle. It takes 2.55 10^-3 s for the bullet to travel the length of the barrel, and it exits the barrel with a speed of 730 m/s. Assuming that the acceleration of the bullet is constant, find the average net force exerted on the bullet
m=22g
is a=0 ? since its constant
v = 730 m/s
t=2.55 * 10^-3
I thought this is F=ma.
But its wrong! I believe im doing this wrong, any suggestions???
