The engine power of a truck is 100 kW, which means that a) the car carries a load of 10 tons at a distance of 10 m

The engine power of a truck is 100 kW, which means that a) the car carries a load of 10 tons at a distance of 10 m b) the car engine works 100 kJ for 1 s) the maximum speed of the car is 100 km / h d) the carrying capacity of the car is 100 kN

According to the definition, power N is a scalar physical quantity that shows the speed of performing mechanical work A. The formula for determining the power of the engine of a truck N is: N = A / t, where t is the time of work.

Power N shows the amount of performed mechanical work A per unit of time t = 1 s.

Therefore, the engine power N = 100 * 10 ^ 3 W means that the engine for a time t = 1 second performs mechanical work A = 100 * 10 ^ 3 J = 100 kJ.
