. If a projectile hits a stationary target, and the projectile
rebounds and travels back the way it came,
A) the mass of the projectile is much less than the mass of the
target.
B) the mass of the projectile is equal to the mass of the
target.
C) the mass of the projectile is much greater than the mass of
the target.
D) nothing can be said about the masses of the projectile and
target without further information.
E) this is an unphysical situation and will not actually
happen.
