Tutorial Exercise
The height of an object tossed upward with an initial velocity of 184 feet per second is given by the formula
h = \(-16t^2 + 184t\), where h is the height in feet and t is the time in seconds. Find the time required for the object
to return to its point of departure.
Step 1
When the object has returned to its point of departure its height is 0 ft, so we want to find t such that
h =
In other words, we want to solve the equation
\(0 = -16t^2 + 184t\).
