At the bottom of the circle, the ball is being pulled upward by tension in the rope and downward by its own weight, so that the net force on it is
∑ F = 450 N - (0.75 kg) g = (0.75 kg) a
where a is centripetal acceleration. At this maximum tension, the ball has a maximum centripetal acceleration of
a = (450 N - (0.75 kg) g) / (0.75 kg) = 590.2 m/s²
Then its maximum tangential speed v is such that
a = v² / (1.0 m)
⇒ v = √((1.0 m) a) ≈ 25 m/s
I'm really sorry but you didn't gave any options...
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.
