complete the statement: in recoil

Question

a)the initial momentum is zero
b)the object sticks together after collision
c)the total kinetic energy is conserved
d)the final speeds of the object are the same

b) is wrong. I think it's either c) or d) but i'm going to go with c).

Answer 1

Not c. A bullet leaves a gun, the gun recoils. The initial momentum is zero, the final total momentum is zero.
