1. The problem statement, all variables and given/known data An 19-g bullet is shot vertically into an 5-kg block. The block lifts upward 5 mm. The bullet penetrates the block in a time interval of 0.001 s. Assume the force on the bullet is constant during penetration. The impulse on the block due to capture of the bullet is closest to: 2. Relevant equations Impulse = P_2 - P_1 3. The attempt at a solution 1/2(mbullet + mblock)v2^2 = (mbullet + mblock)gy v2 = sqrt(2gy) v1 = ((mbullet + mblock)/mbullet)*v2 Impulse = m2v2 - m1v1 Comes out wrong, and didn't use the time given. I modeled my solution after a ballistic pendulum problem. Any pointers?
