Question 87

An electric winch motor is supplied with 8500 J of total energy. During this time, the efficiency of the motor is 65%.

Calculate the useful energy transferred by the motor.

Use the equation:

efficiency=useful energy transferredtotal energy supplied \text{efficiency} = \frac{\text{useful energy transferred}}{\text{total energy supplied}} efficiency=total energy supplieduseful energy transferred​
