A19g bullet is traveling at 334m/s when it strikes a block of wood. if the block of wood exerts a friction-like force of 50,000 n opposing the motion of the bullet, how far will the bullet penetrate the block of wood? (assume the bullet does not drop in height at all.)

For the bullet,  the net force on the bullet: an fbd would look like a dot with a horizontal "friction" force protruding from one end.by newton's 2nd law: we can solve for acceleration since we know  and .we know that  (final velocity is bullet not moving), . we can use the following kinematic equation to get  , or the displacement.so it penetrates  m.
