A cliff diver falls forward from a cliff 130 feet above the ground. His position function is given by s(t) -16t^2 +130, where t is measured in seconds and s is measured in feet. After how many seconds will he be traveling at -40 ft/s?

Take the derivative of s(t) and set it equal to -40 ft/s then solve for time.
