The official softball is a smooth-seam ball 12 inches in circumference, weighing between 6.25 and 7 ounces (177 and 198 grams)
grams
no. the weight is 6 to 7 oz. Inches is a distance
177 lbs = 80.29Kg
6 to 7 oz
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.
Strictly a matter of which possesses the greater mass. If the softball has less mass than a basketball, it must weigh less.

Unfortunately, your list of situations got lost, so there's no way for me to choose the correct one. But clearly, since the baseball's mass is only half the softball's mass, the baseball needs double the softball's speed in order to have the same momentum.
I don't think so..a softball is bigger. More mass means more resistance.
yes the softball is heaver bc of the bigger it is. now i don't think a softball is heaver of air mass. but yes a softball is heaver!

If you are reffering to speed, there is no calliber that can beet the .177. You can get a .177 gun that shoots anywhere from 150 FPS to 1200 FPS. There is a catch though, because energy is calculated by mass X exelleration, you can learn that where the .177 has high speed, it has very low mass. If you got a .20, .22, or .25 calliber gun, than you would have very low speed but very high mass.
