73 -- In the figure below, the total mass of the tractor and its load is 2 tons, and the tractor moves on a slope at angle $37^\circ$. A constant force of $6000\,\text{N}$ is applied to it. If the friction force applied to the tractor is $4000\,\text{N}$, and with this condition the tractor moves 5 meters horizontally and vertically along the slope, how many joules does the lateral kinetic energy of the tractor change? ($\cos 37^\circ = 0.8$)
