for the length.
Example: The Equation off Linear Motion. The equation of motion
for a free-falling object is:
d = v0t + Vigt2
where d is the distance, v0 is the initial velocity, f is the time, and g is
the acceleration due to gravity. Setting the equation equal to zero and
simplifying it yields
0 = n>0 + #/2) ~ d.

The acceleration due to gravity, g, is included as a variable to allow
you to change it for working with different units:
g = 9.8 m/s2 = 32.2 ft/s2.
Enter the above program (LBL M). Calculate how far an object falls in
5 seconds, starting from rest.
