An object is dropped from a height of A (m) (free fall). If the speed of the
object when it reaches the ground is B (m/s) and gravitational acceleration is
C = 9.8 (m/s
2
), we can set up the following relation: (1/2) B
2
= CA.
Determine the speed of the object when it reaches the ground if it is dropped
from a height of 30 meters.
Convert the speed to kilometers per hour.
The SOLVE function lets you solve for the value
of a given relation without changing its form.
A unit conversion function (fx-570MS/fx-991MS only) lets
you convert from meters per second to kilometers per hour.
