750 million years ago, there was enough Uranium-235 present in Oklo, Gabon to have a natural fission reactor occur and generate

Let us denote as the highest acceleration of the truck by itself. The force generated by the engine to propel the truck in this scenario is

where m is the mass of the truck alone.

Upon attaching a bus that has double the mass of the truck, the total mass of the entire system (truck+bus) becomes (m+2m)=3m. In this situation, the force generated by the engine is

where a2 represents the new acceleration. 
Since the engine remains unchanged, the force generated stays the same, allowing us to set the force equations equal to each other:

and solving for a2 gives us:

answer:

Given: Speed of the sports car, v = 85 mph = 37.99 m/s. Radius of curvature, r = 525 m. Let normal weight be denoted as n and apparent weight as a. The apparent weight can be described by:... or... Consequently, this provides the necessary solution.
