a bullet is fired from a gun.the force on the bullet is given by F=600-2*10^5t where F is in Newton and t is in sec. The force on the bullet becomes zero as soon as it leaves the barrel.what is the avg impulse imparted to the bullet

A) 8N s

B)0

C)0.9N s

D)1.8N s

wen F=0, 600-2*10^5t=010^5t=300t=(log3+2)/5impulse is integral Fdtintegral (600-2*10^5t)dt thev limits of integration are frm 0 to (log3+2)/5
