A bullet is fired from a gun the force on the bullet is given by f equals to 600 - 2 into 10 raise to 5 t where is newton's and 3 seconds the force on the bullet becomes zero as soon as it leaves the barrel what is the average impulse imparted by the bullet

F=600−2×105t
0=600−2×105 t
t=600/(2×105)
t=3×10 −3 s
t=3milliseconds.
Time is taken by bullet leave the barrel is 3 milliseconds
F.idt=(6t×105 t).dt
J=[600t−(2×105 2t² )]
J=[600×(3×10 −3 )−(2×10 5 × 2(3×10 −3 ) 2 )]
J=0.9Ns
