In terms of thermal energy, why does a bottle of soda left in the sun have a higher temperature than one left in an ice chest?

The bottle of soda that is left in the sun absorbs more radiant energy therefore increasing its kinetic energy 

The total displacement of the car after five hours - 0km.

Displacement -

Displacement is a vector quantity that refers to the object's overall change in position.change in final position from its initial positioncalculating the distance between an object's initial position and its final position.In physics terms, displacement is referred to as the variable s. The official displacement formula is as follows:

                 s = sf – si.

where, s = displacement.

In the given graph there is a change in distance covered with the time that are:

after two hours it reaches 15 km away from the initial pointafter 4 hours car reaches 20 km away from the initial pointAfter 5 hours it returns back to the initial point.

Thus, the displacement would be 0 km as the final point and initial point are the same.
