The engine power of a truck is 100 kW, which means that the car can carry a load of 10 tons at a distance of 10 MB.

The engine power of a truck is 100 kW, which means that the car can carry a load of 10 tons at a distance of 10 MB. the engine performs work of 100 kJ for 1 s. the maximum vehicle speed is 100 km / h. carrying capacity of the car 100kN

From the definition of power, we know that power is the ratio of work performed to a period of time. The unit of power, watt, is defined as the power at which work of 1 Joule is done in 1 second. Thus, a motor with a power of 100 kW will perform work of 100 kJ in 1 s. The correct answer is “B”.
