Question

What is the magnitude of centripetal acceleration for a 28 grams object attached to a 0.8 m radius string spinning at a constant velocity of 2.5 m/s?

Answer 1

Centripetal acceleration is `"7.8 m/s"^2` (rounded to 2 significant figures)

Explanation:

Centripetal acceleration `=v^2/r = ("2.5 m/s")^2/"0.8 m" = "7.8125 m/s"^2`
