too easy
It certainly wasn't simple, I mean I'd never expect to see anything so involved (using integrating factors etc) in an A-Level exam (at least not for AQA) and the context was slightly unusual compared to the norm of a falling hailstone or a water-powered truck, but it was a very good question.
