What is the efficiency of a ramp if 2,000 joules of energy results in 1,200 joules of work?(1 point) Responses 32% 32% 80% 80% 24% 24% 60% 60%

1 answer

To calculate the efficiency of the ramp, you can use the formula:

\[ \text{Efficiency} = \left( \frac{\text{Work Output}}{\text{Energy Input}} \right) \times 100% \]

In this case:

  • Work Output = 1,200 joules
  • Energy Input = 2,000 joules

Substituting the values into the formula:

\[ \text{Efficiency} = \left( \frac{1,200}{2,000} \right) \times 100% \]

\[ \text{Efficiency} = 0.6 \times 100% = 60% \]

So the efficiency of the ramp is 60%.
