What is the efficiency of a ramp if 2,000 joules of energy results in 1,200 joules of work? (1 point)
80%
24%
60%
32%
To calculate the efficiency of the ramp, you would use the formula:
Efficiency = (Output/Input) x 100%
In this case:
Output = 1,200 joules
Input = 2,000 joules
Efficiency = (1,200/2,000) x 100% = 0.6 x 100% = 60%
Therefore, the efficiency of the ramp is 60%.
