A bullet of mass 1.8 X 103 kg is moving at +500. m/s when it impacts a tree stump. It penetrates into the stump 6.00 centimeters before coming to rest.
1. Assuming the acceleration to be constant, calculate the force (including direction) exerted by the stump on the bullet.

Vf^2=Vi^2+2ad
but a= Force/mass
solve for force.
