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? The object strikes the ground at seconds (it is a whole number or integer!)

Where is the object at 0 seconds (before launch)

Where is the object at 1 second after launch?

Where is the object 10 seconds after launch?
