Question 480853: An object is thrown upward from the top of a 160 foot building with an initial velocity of 48 feet per second. The height h of the object after t seconds is given by the quadratic equation h= 16t2+48t+160. When will the object hit the ground?

h=0 when it reaches the terrace height on its way down



solve using quadratic formula






The square root is negative which is absurd.
The equation should be


a = -1,b = 3,c = 10


(ignore negative number)

t = 5
The object will hit the ground in 5 sec
