Answer:
The atomic mass unit is 1/12 of an atom of carbon 12, and is a very small amount to represent in kilograms:

is atomic mass unit.
This is why the benefits of the atomic mass unit is that it makes the representation of atomic masses easier in terms of the simplicity of the numbers that are used to represent the masses. Also using the atomic mass unit it is easier to compare the masses of different atoms, These numbers would be very small and would require negative powers of 10 to represent them, so it is more convenient to use the atomic mass unit.
The formula we need to use is displacement.
, where xf is final position and xi is initial position.
We report the final position of 5 and the displacement of 2 so the formula is now:
.
So the initial position of truck A is 3.
Hope this helps.

KE = 1/2mv^2
KE = 1/2 (5kg)(3m/s)
KE = 22.5 J
