Problema Solution
an objects heighty in feet above the ground after falling for t seconds is given by the equation y= 16xsquared + h, where h is the height in feet. Use this equation to determine how long it would take a penny to drop from the top of a building that is 2,717 ft high.
Answer provided by our tutors
Solution: The height is Y, the Time used is T, H = 2,717Ft
the equation is Y=H-16t^2, when the penny heat the ground the height "Y" = 0
So Y = 2717 - 16t^2,
2717=16t^2, t =13s
