Casio CLASSPAD II User Manual

If an object, such as a ball, is dropped from a initial height, c, the height, h, in feet, as a
function of time, t, in seconds, can be modeled by h = -16t
2
+ c.
If the object is tossed upwards with an initial velocity, v, then the model becomes
h = -16t
2
+ vt + c. These models ignore air resistance.
