In an effort to rev up his lesson, Mr. H does a demonstration with a bucket of water tied to a string. The bucket and water have a mass of 3.0 kg. Mr. H whirls the bucket in a vertical circle such that its acceleration is 17.5 m/s/s at the top of the loop and 43.0 m/s/s at the bottom of the loop.
(Use g = 10 N/kg)
Determine the force of gravity acting upon the bucket.
