How powerful does the motor of a mechanical toy develop if it performs work of 120 J in 1 minute?

The motor power of a mechanical toy can be calculated using the formula:
N = A / t, where N is the power of the motor (W), A is the work done by the motor (A = 120 J), t is the operating time of the motor (t = 1 min = 60 s).
Let’s calculate the power of the motor of a mechanical toy:
N = A / t = 120/60 = 2 W.
Answer: The power of the motor of a mechanical toy is 2 W.
