$\cdot$ Three objects $A, B,$ and $C$ are moving as shown in Fig-
ure $8.35 .$ Find the $x$ and $y$ components of the net momentum
of the particles if we define the system to consist of (a) $A$ and
$C,$ (b) $B$ and $C,$ (c) all three objects.

$\cdot$ The speed of the fastest-pitched baseball was $45 \mathrm{m} / \mathrm{s},$ and the
ball's mass was 145 $\mathrm{g}$ . (a) What was the magnitude of the mo-
mentum of this ball, and how many joules of kinetic energy did
it have? (b) How fast would a 57 gram ball have to travel to have
the same amount of (i) kinetic energy, and (ii) momentum?

$\bullet$ The magnitude of the momentum of a cat is $p .$ What would
be the magnitude of the momentum (in terms of $p )$ of a dog
having three times the mass of the cat if it had (a) the same
speed as the cat, and (b) the same kinetic energy as the cat?

Recoil speed of the earth. In principle, any time someone
jumps up, the earth moves in the opposite direction. To see
why we are unaware of this motion, calculate the recoil speed
of the earth when a 75 kg person jumps upward at a speed of
2.0 $\mathrm{m} / \mathrm{s} .$ Consult Appendix E as needed.

Baseball. A regulation 145 g baseball can be hit at speeds of
100 mph. If a line drive is hit essentially horizontally at this
speed and is caught by a 65 $\mathrm{kg}$ player who has leapt directly
upward into the air, what horizontal speed (in $\mathrm{cm} / \mathrm{s} )$ does he
acquire by catching the ball?
