How much power is used to lift the load?
Explanation:
Power is the energy consumed to do work in unit time. It is calculated by dividing the work done with the time it took for the work to be done.
It is expressed as:
Power = Work / Time = Force x Distance / Time
Given that the force is 160 N, distance is 1 m, and time is 0.5 s, we can calculate the power:
Power = 160 N (1 m) / 0.5 s = 320 W
Therefore, the correct answer is the third option, which is 320W.
Hope this answers the question. Have a nice day.
