A penny is dropped off the Empire State Building, which is 1250 feet tall. If the penny’s pathway can be modeled by the equation h= -16t^2+1250, how long would it take the penny to strike a 6 foot tall person?
h = -16t2 + 1250
Since h = 6 ---> 6 = -16t2 + 1250
16t2 = 1244
t2 = 77.75
t = sqrt(77.75) ---> 8.82 sec (ignore the negative square root)
