Answer 1

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

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

In this case:

• Useful Output Energy (work done) = 1,200 joules
• Input Energy = 2,000 joules

Now, plug in the values:

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

\[ \text{Efficiency} = \left( 0.6 \right) \times 100 = 60% \]

So, the efficiency of the ramp is 60%.
