Problema Solution
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
