LONG PR- 12) A gyroscope spinning at a rate of 35.0 rad/s decelerates at 0.750 rad/s². How many seconds does it take to come to a stop, and how many revolutions does it complete during this time? 13) A beach ball has a diameter of 40.0 cm and a mass of 200 g. If a fully-submerged beach ball is fastened to the bottom of a pool using a string, what is the tension in the string? Hint: Start by first drawing a force diagram.
