Calculation of Tractive Force and Speed

To find the tractive force and speed of the locomotive, we can use the following formulas:

1. Tractive Force (F) = Power (P) / Velocity (V) 2. Velocity (V) = Distance (D) / Time (T)

Given: - Power (P) = 600 W - Distance (D) = 400 m - Time (T) = 30 s

Let's calculate the tractive force and speed of the locomotive.

1. Tractive Force (F): - Substituting the given values into the formula: F = P / V - F = 600 W / V

2. Velocity (V): - Substituting the given values into the formula: V = D / T - V = 400 m / 30 s

Now, let's calculate the tractive force and speed.

Calculation:

1. Tractive Force (F): - F = 600 W / V

2. Velocity (V): - V = 400 m / 30 s

Using the given values, we can calculate the tractive force and speed of the locomotive.

Solution:

1. Tractive Force (F): - F = 600 W / V - F = 600 W / (400 m / 30 s) - F = 600 W / (13.33 m/s) - F ≈ 45 N

2. Velocity (V): - V = 400 m / 30 s - V ≈ 13.33 m/s

Therefore, the tractive force of the locomotive is approximately 45 N, and the speed of the locomotive is approximately 13.33 m/s.

Please note that these calculations are based on the given information and assumptions.
