Which item has the smallest mass among baseball, softball, golf ball, and tennis ball?

• A. Baseball (143.50 g)
• B. Softball (178.60 g)
• C. Golf Ball (43.60 g)
• D. Tennis Ball (57.0 g)

Answer: (C)

To find the smallest mass, compare the masses directly since they’re all in the same unit (grams). Baseball is about 143.50 g, softball about 178.60 g, golf ball about 43.60 g, and tennis ball about 57.0 g. The golf ball’s 43.60 g is smaller than the other three values, so it has the smallest mass. This also fits the general idea that golf balls are lighter than the other common balls listed.
