Question

the electric motor of a model train accelerates the train from rest to 0.560 m/s in 34.0 ms. the total mass of the train is 835 g. find the average power delivered to the train during its acceleration.

Answer 1

The average power delivered to the train during its acceleration is 8.689 watts.

Step-by-step explanation:

The average power delivered to the train during its acceleration can be calculated using the formula:

Power = (mass × acceleration × distance) / time

Given that the train's mass is 835 g (or 0.835 kg), its acceleration is 0.560 m/s², and its time of acceleration is 34.0 ms (or 0.034 s), we can substitute these values into the formula to find the average power.

Power = (0.835 kg × 0.560 m/s² × 0.560 m) / 0.034 s = 8.689 W

Therefore, the average power delivered to the train during its acceleration is 8.689 watts.
