Final answer:
The efficiency of the ramp is calculated as 25%, which is found by dividing the output work (24J) by the input work (96J) and multiplying the result by 100. Therefore, the efficiency of the ramp is 25%.
Step-by-step explanation:
The efficiency of a machine is calculated by dividing the output work by the input work and then multiplying by 100 to get a percentage. In this case, the student is asking, What is the efficiency of a ramp if the input work is 96J and the output work is 24J? To find the answer, we would use the formula:
Efficiency = (Output Work/Input Work) × 100%
Substituting the given values:
Efficiency = (24J/96J) × 100%
Efficiency = 0.25 × 100%
Efficiency = 25%
Therefore, the efficiency of the ramp is 25%.
