v1 = 95 mi/h
v2 = 67.2 mi/h
mass remains the same: compare the factor v2 in the equation:
A baseball weighs 5.13 oz. What is the kinetic energy, in joules, of this baseball when it is thrown by a major league pitcher at 95.0 mi/ h?
By what factor will the kinetic energy change if the speed of the baseball is decreased to 67.2 mi/h?
