If an object is propelled upward from ground level, its height in meters after t seconds is given by h=-9.8t^2+88.2t During what interval of time will the rocket be height than 176.4m.
h = -9.8t^2 + 88.2t
We want h to be greater than 176.4 m
Therefore -9.8t^2 ...
Neat, step-by-step solution is provided.
