Answer: 48.08 watts
Explanation:
power needed = ?
Work done = 462 joules
Time taken = 9.61 seconds
Recall that power is the rate of energy expended or workdone per unit time. i.e Power = Workdone / Time
Power = 462 joules / 9.61 seconds
Power = 48.08 watts
Thus, 48.08 watts of power is needed to the work.
