Final answer:
The centripetal acceleration of a point on the edge of an ice skater's clothing with a radius of 0.80 m, spinning at 5 rev/s, is approximately 789.57 m/s². The provided calculation uses the formula for centripetal acceleration with an angular velocity converted to radians per second.
Step-by-step explanation:
The student's question deals with the concept of centripetal acceleration, which is an important topic in physics, specifically under the section of circular motion. To calculate the centripetal acceleration 'a' of a point on the edge of an ice skater's clothing, we use the formula a = rω², where 'r' is the radius of the circle that the point traces (0.80 m in this case) and ω is the angular velocity in radians per second. Given that the skater spins at 5 revolutions per second (rev/s), we need to convert this to radians per second. Since one revolution is 2π radians, 5 rev/s is equivalent to 5 × 2π rad/s, which is around 31.4 rad/s. Now we can plug these values into the formula:
a = rω² = 0.80 m × (31.4 rad/s)² ≈ 0.80 m × 986.96 rad²/s² = 789.568 m/s²
Therefore, the centripetal acceleration experienced by a point on the edge of the skater's clothing is approximately 789.57 m/s². This value is not present in the given choices, suggesting there might have been a typo in the question or the answer choices provided. Yet, it's crucial to note that the concept behind this calculation remains the same irrespective of the peculiarity of this situation.
