Question

An object is launched at 39.2 meters per second (m/s) from a 42.3-meter tall platform. The equation for the object's height s at time t seconds after launch is s(t) = -4.9t^2 + 39.2t + 42.3 where s is in meters. Create a table of values and graph the function. Approximately when will the object hit the ground?
Explain

Answer 1

Just add the numbers up and see if that works
