The direction of force depends on wether we are considering the force by hammer or the reaction force.
SInce in that answer i have taken the outward velocity as positive thus the force which will come as -24/0.002 will be the reaction force on hammer.
FOr situations like this always imagine the direction of force and velocity and compare it with real life situations.
Always mind the sign.
