A 1.50 lb оbject is аttаched tо а vertical spring and vibrates with a periоd of 2.50 seconds when set in motion. How much additional weight (in pounds) must be added to the spring to slow the vibrations down so that the new period is 3.50 seconds? Make sure to pay attention to the difference between mass and weight. Assume this experiment takes place on Earth.
