Horatio stands on a platform 7.8 m above the ground and drops a ball straight down. At the same moment, Amelia uses a spring-loaded device on the ground to launch a dart straight up toward the ball. The dart is launched at 16.0 m/s. Find the time and height of the collision by simultaneously solving the equations for the ball and the dart.
