Power Practice Worksheet.docx

7. We know that we want the student to be able to generator 50,400J of energy, and the problem says they can continuously produce 30W of power which is 30J/s. Use the given information and the power equation to solve for the time (Δt): P = ΔE/t, 30J/s = 50,400J/Δt, solving for Δt = (50,400J) / (30J/s) = 1,680s or. 28min. ................
