10,000 W of power is used to move a spoon for 10 s. How much work is done on the spoon?

The work done is 100,000 Joule

Explanation:

Work and Power

Work is the amount of energy transferred by a force.

If both the force F and displacement s are parallel, then we can use the formula:

W = F.s

Power is the amount of energy transferred or converted per unit of time. In the SI, the unit of power is the watt, equal to one joule per second.

The power can be calculated as:

Where W is the work and t is the time.

We know the power needed to move a spoon is P=10,000 Watt and it took a time of t=10 s. The work done on the spoon is calculated by solving for W:

W = Pt

W = 10,000 Watt * 10 sec

W = 100,000 Joule

The work done is 100,000 Joule
