The engine of a train produces a force of 3000N when moving at 30.ms-1. calculate the power of the engine
Answer Details
The power of the engine can be calculated by multiplying the force produced by the engine with the speed of the train. The formula for power is:
Power = Force x Speed
Using the given values, we can calculate the power of the engine as follows:
Power = 3000 N x 30 m/s
Power = 90000 W
Therefore, the power of the engine is 9.00 x 10^4 W.
To summarize, the power of an engine is the product of the force produced by the engine and the speed of the object. In this case, the engine produces a force of 3000N and moves at a speed of 30 m/s, giving a power output of 9.00 x 10^4 W.
