A penny is dropped from a 512-foot tall tower. The equation 512 - h = 16t2 can be used to find the height h of the penny after falling for t seconds. Estimate the height of the penny after falling 2 seconds.

So this is pretty short and sweet. Simply add h to both sides, and subtract 16t^2 on both sides of the equation. Then just plug in 2 for t and you will find h(2), which represents the height at 2 seconds.
