The efficiency of a ramp can be calculated using the formula:
Efficiency = (Useful Energy Output / Total Energy Input) * 100
In this case, the useful energy output is 1,200 joules and the total energy input is 2,000 joules.
Efficiency = (1,200 / 2,000) * 100 = 60%
Therefore, the correct answer is:
60%
What is the efficiency of a ramp if 2,000 joules of energy results in 1,200 joules of work?(1 point)
