Does a baseball of softball have more kinetic energy when thrown at 35mph?
KE = 1/2mv2, where m is mass in kg, and vis velocity in m/s. Since both the baseball and the softball are thrown at the same velocity, the difference in KE comes down to mass. A baseball has a mass of 0.142kg - 0.149kg, and a softball has a mass of 0.177kg - 0.198kg. Therefore, since the softball has the greater mass, the softball would have more kinetic energy. The 2 after the v is supposed to be a superscript and is supposed to mean velocity squared.
