Your electricity usage for a one month period is 500 kilowatt-hours. Assuming one month is equal to 30 days and that the electricity usage is uniform across the whole month, what would be the velocity of a 1 kg mass if it was given the kinetic energy equivalent to one day's electricity usage?

Answer 1

Divide 500 kW-h by 30 for the daily energy usage. Then convert that to Watt-seconds (joules). You should end up with 60 million.

Then set that equal to (1/2) M V^2 and solve for V.
