Students in the lab (see Figure 10.5) measure the speed

of a steel ball to be 8.0 m/s when launched horizontally

from a 1.0-m-high tabletop. Their objective is to place a

20-cm-tall coffee can on the floor to catch the ball. Show

that they score a bull's-eye when the can is placed 3.2 m

from the base of the table.
