How far has a car with a mass of 10 tons moved from a state of rest, if at the same time the resultant force was a work of 2000 kJ?

How far has a car with a mass of 10 tons moved from a state of rest, if at the same time the resultant force was a work of 2000 kJ? The car was moving with an acceleration of 1 m / s ^ 2.

All the work done by the resultant force was used for kinetic energy. Those. :
mV ^ 2/2 = A
Find V:
V = sqrt (2A / m) = sqrt (400) = 20m / s.
Let’s write the equation of speed:
V = a * t; hence t = V / a = 20/1 = 20 sec.
Find S:
S = at ^ 2/2 = 1 * 400/2 = 200m
