Here
m = 20gm
v = 300m/s
=> Kinetic Energy = 1/2 * 0.020 * (300)^2 = 900J
Work done = Force(F) * Displacement(s)
> 900J = F * 0.03
> F = 3*10^4 N
Please Correct me if i am wrong. My answer is Positive but in your book its negative.

answer will be obviously negative as the acceleration is negative becoz u can clearly see that bullet has stopped from some initial speed so it is decelerating..
Ok.. Thanks.
