What is the efficiency of a ramp if 2000 J of energy result and 1200 J of work
The efficiency of a ramp can be calculated using the formula:
Efficiency = (Useful energy output / Total energy input) x 100%
In this case, the useful energy output is the work done (1200 J) and the total energy input is the energy required to achieve that work (2000 J).
Efficiency = (1200 J / 2000 J) x 100% = 0.6 x 100% = 60%
Therefore, the efficiency of the ramp is 60%.
