1. The problem statement, all variables and given/known data The energy of a system increases at a rate of 3.5t + 6.2t^2, in joules. What is the instantaneous power at t=3.1 s? 2. Relevant equations P=dW/dt J/s=watt 3. The attempt at a solution dW=3.5 + 12.4t P=(3.5 + 12.4t joule) / (3.1s)=1.12 + 4t, in watts Yes/ no???
