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 = 0. In other words, we want to solve the equation
-16t^2 + 184t = 0.
