To find the average power delivered to the model train during its acceleration, we can follow these steps: ### Step 1: Identify the given values - Final velocity (V_final) = 0.620 m/s - Initial velocity (V_initial) = 0 m/s (since it starts from rest) - Time (t) = 21.0 ms = 21 × 10^(-3) s - Mass (m) = 875 g = 0.875 kg (convert grams to kilograms) ...
