Can someone give me a simple example of a quadratic word problem that can be graphed?

OpenStudy (alexwee123):

An object is launched at 19.6 meters per second (m/s) from a 58.8-meter tall platform. The equation for the object's height s at time t seconds after launch is s(t) = –4.9t2 + 19.6t + 58.8, where s is in meters. When does the object strike the ground?
