1. Sitting in the outfield bleachers, 170 m from home plate , you see a
bafter hit the ball for a home run. How long after you see the ball hit do
you hear the crack of the bat?
2. At Zion National Park a loud shout produces an echo 1.75 s later
from a colorful sandstone cliff. How far away from the shouter is the
clift? (Hint: The echo reflects off the distant cliff and returns to its
source. Use the equation d = vt to solve for distance.)
