One ball is dropped at rest from a height of h = 65 m. At the same time, another ball is thrown upward from the ground with initial velocity v2 = 31 m/s. It takes Δt time for them to meet on the way.  Express the displacement of the ball falling down, Δy1, when the two balls meet in terms of Δt and a.  Express the displacement of the ball going upward, Δy2, when the two balls meet in terms of v2, a, and Δt.  Calculate the numerical value of Δy2, in meters, which represents the height at which the two balls meet.
