It takes 8 seconds for a pulley system to lift a load that weights 400N to a height of 10 m. How much power is required?.
mariarad [96]

Answer:

C. 500 watts

Explanation:

power is defined as the rate of work done

power=\frac{work.done}{time}

When a force causes a object to move, work is being done on the object by the force.

work.done=force*displacement\\=400*10\\=4000J

power=\frac{4000J}{8s}\\=500 W
