1. The problem statement, all variables and given/known data A string with linear mass density of 0.143 kg/m is under a tension of 107 N. How much power must be supplied to the string to generate a sinusoidal wave of amplitude 1.97 cm and frequency 107 Hz? 2. Relevant equations V=√F/μ V=ω.A 3. The attempt at a solution I found V and ω by using equations above but don't know how to calculate power.
