Question

A small electric motor has an efficiency of 35%. In lifting a small object, it produces 12 J of mechanical energy input. Calculate the total useful mechanical energy output of the motor.

Answer 1

\[Efficiency = \frac{output}{input} * 100\]Can you solve it from here?

Answer 2

I can try

Answer 3

All should have to do is plug in the value and solve for the output.

\[35=\frac{output}{12J}*100\]
