Aball is thrown directly up in the air from a height of 5 feet with an initial velocity of 60 ft/s. ignoring air resistance, how long until the ball hits the ground? use the formula where h is the height of the ball in feet and t is the time in seconds since it is thrown. round your answer to the nearest tenth.
