Question

A 50 kW tractor moves at a speed of 2.5 m/s. What is the traction force of the tractor?

Answer 1

In order to calculate the force, we can use the formula below:

`P=F\cdot v`

Where P is the power (in W), F is the force (in N) and v is the velocity (in m/s).

So we have:

`\begin{gathered} 50000=F\cdot2.5\\ \\ F=(50000)/(2.5)\\ \\ F=20000\text{ N} \end{gathered}`

Therefore the traction force is 20 kN.
