Question 33248
HELLO!!!  THIS IS A CREATIVE ASSIGNMENT! YOU'RE SUPPOSED TO THINK ONE UP YOURSELF LOL.... w/e  well speed has a constant (k) of gravity, so when something falls straight down its speed of falling is linear, mostly time vs speed things, like a car that uses up gasoline.. anything with a set constant and two variables.  IE, the gasoline usage (milage) is constant and the variables are the miles it goes and the gasoline left.
