A student stands at the edge of a cliﬀ and throws a stone horizontally over the edge with a speed of 18.9 m/s. The cliﬀ is 77.2 m above a ﬂat, horizontal beach. At impact, what is its speed? I calculated the time it takes to reach the bottom, which was 3.967~ seconds. I figured the speed would just be 18.9 m/s, the same as the original speed, but something tells me that's not right. Can someone point me in the right direction please?
