Homework Statement
9.6 A table-tennis ball is thrown at a stationary bowling ball. The
table-tennis ball makes a one-dimensional elastic collision and bounces back
along the same line. Compared with the bowling ball after the collision, does
the table-tennis ball have (a) a larger magnitude of momentum and more
kinetic energy, (b) a smaller magnitude of momentum and more kinetic
energy, (c) a larger magnitude of momentum and less kinetic energy, (d) a
smaller magnitude of momentum and less kinetic energy, or (e) the same
magnitude of momentum and the same kinetic energy?
