Question 1. A tractor pulls a plough through a field of dry clay. The plough creates a furrow by pulling a blade through the field. The plough has 8 blades and so can plough 8 furrows at once. Each plough need to be 3 cm deep and 12 cm wide. The plough can be modelled as a blade with an angle 52 to the surface of the field. Given that the tractor has a velocity of 28 kph and that dry clay has a density of 1600 direction. Calculate the total force required by the tractor to pull the plough, write your answer, in N, to 3 significant figures. kg m Assume that the tractor is moving in the negative x Question 1.
