1. The problem statement, all variables and given/known data A mass of 0.5kg hangs on a spring. When an additional mass of 0.2kg is attached to the spring, the spring stretches an additional .04m. When the 02kg mass is abruptly removed, the amplitude of the ensuing oscillations of the 05 kg mass is observed to decrease to 1/e of its initial value in 1.0s. Calculate the frequency of the damped oscillations. 2. Relevant equations 3. The attempt at a solution I'm not sure how to start this problem. What I'm looking for is someone to give me a push in the right direction so that I can work the rest! please help me start! Thanks all!
