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) = –4.9t^2 + 19.6t + 58.8, where s is in meters. What is the height of the object when t=0? And when t=5
What is 58.8 meters?
What is 34.3 meters?
