Under the action of a force of 400 N, a mechanical work of 1600 kJ was performed. Determine the path traveled.

Answer: 4 km.
Explanation of the solution to the problem: to solve this problem, you must use the formula for finding a job:
A = F * l, where A is the work of force in J, F is the force of gravity in n, l is the length of movement in m.
Before substituting values in the formula, you first need to translate the data into the SI system:
A = 1600 kJ = 1600 * 1000 = 1600000 J.
Now we substitute the values into the formula and get the following:
l = A / F = 1600000/400 = 4000 m = 4 km.
