Input xf-xo = 260 m, ao = 1g = 9.8 m/ss, and vo=0. Depending on the order that you enter these quantities, you may be presented with two solutions -- choose the one for which vf is negative (downward) also. Read time elapsed as tf-to = 7.28 seconds, and vf = -71.38 meters per second. Change time and distance units with the View menu to convert vf to -159 miles per hour Not a slow pitch! To find out what happened to Joe after he got his glove on a ball (after 5 tries), look at a copy of Fundamentals of Physics, Chapter 2, Page 30, 4th Edition (Wiley, 1993) by Halliday, Resnick, and Walker.
