To calculate the efficiency of the ramp, you can use the formula:
\[
\text{Efficiency} = \left( \frac{\text{Useful Work Output}}{\text{Total Energy Input}} \right) \times 100\%
\]
In this case, the useful work output is 1,200 joules, and the total energy input is 2,000 joules.
\[
\text{Efficiency} = \left( \frac{1200 \text{ J}}{2000 \text{ J}} \right) \times 100\% = 0.6 \times 100\% = 60\%
\]
Therefore, the efficiency of the ramp is **60%**.
\[
\text{Efficiency} = \left( \frac{\text{Useful Work Output}}{\text{Total Energy Input}} \right) \times 100\%
\]
In this case, the useful work output is 1,200 joules, and the total energy input is 2,000 joules.
\[
\text{Efficiency} = \left( \frac{1200 \text{ J}}{2000 \text{ J}} \right) \times 100\% = 0.6 \times 100\% = 60\%
\]
Therefore, the efficiency of the ramp is **60%**.
