These tasks: t (duration of operation of the Volga car) = 2 hours (in the SI system t = 7200 s); A (the work done by the “Volga”) = 144 kJ (144 * 10 ^ 3 J).
To find the power of the Volga car, we will use the formula: N = A / t.
Let’s calculate: N = 144 * 10 ^ 3/7200 = 20 watts.
Answer: The Volga car has a power of 20 watts.
