To calculate the efficiency of a pulley, we need to divide the useful work output by the total energy input and multiply by 100 to express it as a percentage.
Efficiency = (Useful work output / Total energy input) * 100
Given that 5000 joules of energy results in 3000 joules of work:
Efficiency = (3000 joules / 5000 joules) * 100 = 60%
Therefore, the efficiency of the pulley in this scenario is 60%.
What is the efficiency of a pulley if 5000 joules of energy results in 3000 joules of work?

Certainly!
Efficiency = (Useful work output / Total energy input) * 100
Given:
Total energy input = 5000 joules
Useful work output = 3000 joules
Efficiency = (3000 joules / 5000 joules) * 100
Simplifying:
Efficiency = 0.6 * 100
Efficiency = 60%
Therefore, the efficiency of the pulley in this scenario is 60%.
