1. The problem statement, all variables and given/known data During the World Series a ball is hit straight up from the batter’s box and reaches a height of 295 ft. Neglecting air friction, what speed (mph) will the baseball attain if it is caught by the catcher at the same height it was hit? 2. Relevant equations The equation I pull out of this is the one for gravitational potential energy Ug=M*G*H G = 9.81 m/s H = 295 feet = 89.9 m It could also have something to do with the ball having no kinetic energy when it make contact with the bat, then having no gravitational potential energy when the catcher catches it but, I can't figure out how to put these two formulas together. Uk=(1/2)*mv^2 3. An attempt at the problem Ug = 9.81 m/s * 89.9m Ug = 882m/s = 2030m/h (seems unlikely this ball will break mach 1) This would only work if we disregard mass. We've done this in other problems, but it seems very important here.
