this would be considered as an inelastic collision where (m1v1) + (m2v2) = (m1+m2)vf
also the conservation of energy being (∆K +∆U)=0 i tried using the conservation of energy to find v2 as the variable we are looking for is Vf, the speed the bullet leaves the block, and v2 (velocity of the block) is what's missing in the collision equation in order to solve for Vf, although, knowing that the correct answer is 100, these method doesn't the correct answer, it gives a very small value for Vf which doesnt't make sense.
