The lecture Uniform Circular Motion Example by Jared Rovny is from the course Force.
In a demonstration, John used a bucket of water tied to a 1.3meter long string. The bucket and water have a mass of 1.8 kg. John 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? What is the tension force in the string for the two locations i.e. top and bottom?
A 76kg pilot at an air show performs a loop de loop with his plane. At the bottom of the 52m radius loop, the plane is moving at 48 m/s. Determine the normal force acting upon the pilot.
During the spin cycle of a washing machine, the clothes stick to the outer wall of the barrel as it spins at a rate as high as 1800 revolutions per minute. If the radius of the barrel is 26cm, determine the acceleration of the clothes.
