Waec Model Questions Vol1 2025 Agricultural Science Question 28
Practice objective / multiple choice question 28 from the 2025 Waec Model Questions Vol1 Agricultural Science examination.
A farmer intends to plough a 2.5 ha field using a tractor equipped with a 5‑bottom moldboard plough. Each bottom is 0.30 m wide, the soil draft requirement is 2 500 N per metre of plough width, and the implement weight is 1 500 kg with a rolling‑resistance coefficient of 0.05. The tractor can maintain an average field speed of 5 km h⁻¹ and its draw‑bar power is 30 kW. Assuming a power‑train efficiency of 85 %, (i) decide whether the tractor's power is sufficient to pull the plough, and (ii) compute the time required to plough the whole field if it is feasible. Give the time in hours (to two decimal places).
