You are on the 6th floor ( 64 ft above ground) of a burning building and there is no escape except to jump into a deep pool of water below.
Hint: 64 ft was chosen to match up with 32ft/sec^2 - gravity acceleration, making the math quite easy.
How fast will you be traveling when hitting the water below (expressed in MPH).
BTW: this is an important question for those living in (or visiting) a high-rise apartment. Also, you may want to plot an acceleration curve. That way, at a glance, you can determine any speed of impact at any height.
