Determine the work done (in kJ) in moving a truck with a mass of 5811 kg for a distance of 170 m up a slope with a gradient of 1 in 50, if the tractive resistance of the truck is 128 N per tonne.

Answer :

Final answer:

To determine the work done in kJ in moving the truck, calculate the total work done against tractive resistance and up the slope.

Explanation:

To determine the work done in kJ in moving the truck, we need to calculate the total work done against the tractive resistance and the work done to move the truck up the slope. First, we calculate the tractive resistance:

Tractive resistance = (128 N/tonne) * (5811 kg) * (1/1000) = 747.648 N

Next, we calculate the work done to move the truck up the slope:

Work = Force x Distance = (mass x gravitational force x sine of angle) x distance
