The height of a building is 1839 feet. How long would it take an object to fall to the ground from the top? Use the formula d=16t^2
Answer provided by our tutors
d=16t^2 and d = 1839
by solving the equation
16*t^2 = 1839
we find and consider the non-negative solutions only (since time can not be negative number)
t = 10.72 sec
