This is an A.P Physics class which is algebra based and does not use calculus. This problem is really annoying because it is one of the easier questions from the homework but i can't seem to understand the procedure. One kilowatt x hour (kWh) is the amout of work or energy generated when one kilowatt of power is supplied for a times of one hour. Determine the number of joules of energy in one kilowatt x hour. Any suggestions?
