1. The problem statement, all variables and given/known data The problem: A woman standing on a diving board 21 meters above a pool tosses a ball upwards at a speed of 19 meters/second. The ball goes up and then down, splashing into the water below. How long was the ball in the air? What is the ball’s final velocity? 2. Relevant equations v2= v02+2a(x-x0) X = X0 +V0t+(1/2)at2 3. The attempt at a solution So I figured out the height of the ball by using v2= v02+2a(x-x0) and having v = 0 because thats what it is at the peak and re aranged it so it gives me X. I got 39.25 meters. But I don't know how to get the time the ball is in the air. I assume I have to possibly use X = X0 +V0t+(1/2)at2 but im not sure how to get time out of it.
