Question 1147315: Suppose the height h of an object thrown straight upward from the ground is given by
h = 44.1t - 4.9t2, where h is in meters and t is the elapsed time in seconds.
When is the object at a height of 88.2 m as it moves up? Write the exact answer WITHOUT units.

Solve the equation 44.1t-4.9t%5E2+=+88.2.

The numbers look a bit ugly; but they work out nicely.

Or a graphing calculator will give you the answer quickly if you know how to use it....
