## Homework Statement

In an effort to

*rev up*his class, Mr. H does a demonstration with a bucket of water tied to a 1.3-meter long string. The bucket and water have a mass of 1.8 kg. Mr. H whirls the bucket in a vertical circle such that it has a speed of 3.9 m/s at the top of the loop and 6.4 m/s at the bottom of the loop.

Draw a free body diagram for the bucket for each location

## Homework Equations

## The Attempt at a Solution

At the top of the circle the the mass has gravity and tension going downwards, and at the bottom of the circle the mass has gravity downwards and tension upwards. but is there another force acting parallel to the tension and gravity? I think this would be the force that is causing the bucket to move in circular motion but I also think I might be thinking of a centrifugal force which is a fictitious force.
