Let's say for the purpose of this question that a softball pitcher completes one perfect revolution during her fast pitch. The pitcher's arm is 0.81585 m, and she completes her pitch in 0.9s, what is the velocity of the ball as it travels around the arc? Assume she keeps her arm extended throughout the pitch, and round your answer to two decimal points. What is the centripetal acceleration of the softball?
Could you olease help me to solve this?

- Thinking Mathematically: Explore the quantitative dependencies of the acceleration upon the speed and the radius of curvature. Then answer the following questions. Choose the right answer in the parenthesis. For the same speed, the acceleration of the object varies (directly, inversely) with the radius of curvature. For the same radius of curvature, the acceleration of the object varies i(directly, inversely) with the speed of the object. As the speed of an object is doubled, the acceleration is (one-fourth, one-half, two times, four times) the original value. 4. As the speed of an object is tripled, the acceleration is (one-third, one-ninth, three times, nine times) the original value.arrow_forwardA soccer ball kicked by a Real Madrid midfielder leaves the player's foot at a speed of 46 mph at an angle & above the horizontal.
