1. The problem statement, all variables and given/known data 2. Relevant equations KE=½m(ωa)2 3. The attempt at a solution So first I did this: 2.4x10-3= ½ mω2(1.5x10-2)2 To find mω2=21.33 And substitute that into the KE eqn to find the new amplitude, which is 1.30x10-2 But I only did that because that was the only way I could think of. My question is, why is ω constant despite changes in the max KE?
