A point-mass of 17 grams at the end of a massless 20 centimeter long string is rotated at a rate of 5revolutions per second. Find the kinetic energy of the point mass.ergs Note: In the text, all questions use 62.5 pounds/ft as the force per volume density of water.In metric, we would need Newtons/meter. The mass density per volume of water is 1000 kg/m³.To convert this into a force density per volume, we multiply by gravity, approximately 9.8 m/s?. Theresulting quantity is the force density per volume in metric: 9800 N/m³.
