A ball is tossed into the air from height of 8 feet with an initial velocity of 8 feet per second. find the time r(in seconds) i
-Dominant- [34]
For this case we have the following equation:
 -16t + 8t + 8 = 0
 The first thing we must do is rewrite the equation correctly.
 We have then:
 -16t ^ 2 + 8t + 8 = 0
 Solving the polynomial we have:
 t1 = -1/2
 t2 = 1
 We discard the negative root because we want to find the time.
 Answer:
 it takes for the object to reach the ground about:
 t = 1 second
