If you shake the flashlight with an average force of 4.0 N at a speed of 0.80 m/s, what mechanical power do you produce? If you shake the flashlight for 35 seconds, and 75 % of the mechanical energy is converted to electrical energy, how much energy is stored in the capacitor? If the LED lamp draws 0.032 A at 3.1 V, for how much time will the capacitor operate the LED?
