Solving Equations 7-3
g (acceleration due to gravity) is included as a variable so you can change it for
different units (9.8 m/s
2
or 32.2 ft/s
2
).
Calculate how many meters an object falls in 5 seconds, starting from rest. Since
Equation mode is turned on and the desired equation is already in the display, you
can start solving for D:
Try another calculation using the same equation: how long does it take an object to
fall 500 meters from rest?
