Question 1145017: A ball is thrown from a height of 154 feet with an initial downward velocity of 10 ft/s. The balls height “h” (in feet) after “t” seconds is given by the following.
h(t) = 154 - 10t - 16t^2
How long after the ball is thrown does it hit the ground?
Round answer to nearest hundredth
