Question 138375
a building is 540 feet high . neglecting air resistance, the height of an object dropped from the top of this building at time t is given by the polynomial -16t^2 + 540 . Find the height of the object after 5 seconds 
--------------
s(t) = -16t^2 + 540
s(5) = -16(25)+540 = 140 ft (height after 5 seconds)
