A ball is thrown straight down from the top of a 482-foot building with an initial velocity of -15 feet per second. Use the position function below for free-falling objects. s(t) = -16t2 + v0t + s0 What is its velocity after 4 seconds? v(4) =   ft/s What is its velocity after falling 189 feet? v =   ft/s   I found the answer for the first part, which is -143 ft/sec. When I solved the second one, I got -137.88, and it says that is incorrect. So i need help with the second question please
