Wile E. Coyote is holding a “HEAVY DUTY
ACMETM ANVIL” on a cliff that is 40.0 meters
high. The Roadrunner (beep-beep), who is
1.0 meter tall, is running on a road toward
the cliff at a constant velocity of 10.0 m/s.
Wile E. Coyote wants to drop the anvil on the
Roadrunner’s head. How far away should the
Roadrunner be when Wile E. drops the anvil?
O Answer: 28.2m
