The power \(P\) of the train is given by the formula:

\(P = F \times V\)

where \(F\) is the force (resistance) and \(V\) is the speed.

Given:

• \(P = 1330 \text{ kW} = 1330000 \text{ W}\)
• \(F = 28 \text{ kN} = 28000 \text{ N}\)

Substitute these values into the formula:

\(1330000 = 28000 \times V\)

Solve for \(V\):

\(V = \frac{1330000}{28000} = 47.5 \text{ m s}^{-1}\)
