a window washer is suspended 38 feet below the roof of the 1127 foot tall center in chicago. if the window washer drop an object from this height, the objects height h after t seconds is given by the equation

h=16t^2+1089

Find how many seconds pass before the object reaches the ground

Answer provided by our tutors

It hits the groundIt hits

It hits the ground when h = 0


h=-16t^2+1089 = 0

16t^2 = 1089

4t = 33

t = 8.25 seconds

 the ground when h = 0

h=-16t^2+1089 = 0

16t^2 = 1089

4t = 33

t = 8.25 seconds when h = 0It hits the ground when h = 0

h=-16t^2+1089 = 0

16t^2 = 1089

4t = 33

t = 8.25 seconds

h=-16t^2+1089 = 0

16t^2 = 1089

4t = 33

t = 8.25 seconds
