Neco Model Questions Vol1 2020 Agricultural Science Question 41
Practice objective / multiple choice question 41 from the 2020 Neco Model Questions Vol1 Agricultural Science examination.
An agricultural tractor is to pull a plough that requires a drawbar pull of \(1500\ \text{N}\). The total mass of the tractor together with the plough is \(2000\ \text{kg}\). The field has a \(3\%\) slope and the rolling‑resistance coefficient of the soil is \(0.04\). The tractor will travel at a speed of \(5\ \text{km h}^{-1}\). Assuming a drivetrain efficiency of \(85\%\), calculate the minimum engine power (in kW) that the tractor must develop.
