Answer:

0.048 kgm/s, 6.88 kgm/s

Explanation:

m = 0.003 kg, M = 0.43 kg, v = 16 m/s

The momentum of a table tennis ball = mv = 0.003 * 16 = 0.048 kgm/s

The momentum of a soccer ball = Mv = 0.43 * 16 = 6.88 kgm/s

The two balls have same speed, but different masses. A table tennis ball has smaller mass, so the momentum is smaller too.

What were the Anasazi like?
coldgirl [10]
The Anasazi were the ancestors of the modern-day Pueblo people of Arizona and New Mexico. They were not considered a tribe, though their descendents today comprise the federally recongized Navajo Nation. Contemporary Pueblo people view the term "Anasazi" as an ethnic slur because it translates as "ancient enemy" in the Navajo language. Everything we know of these Indians comes from archaeological finds. They were suburb craftsmen and the things they made were meant to last. The homes they built, as well as pieces of their craft work and clothing, still exist today, 1800 years after they were made. Studying the early Pueblo people has given researchers a good picture of what life was like for them and other early Native Americans who are ancestors of the modern-day tribes.
