The question looks quite straightforward

A 1000 kg car travels up a 15° Hill at a constant speed of 80 kmh^-1. Calculate the power of the engine (ignore resistive forces). But when broken down into a network of steps its not so simple.

It's my latest project. A revision website that guides a student through the process of problem solving by breaking problems into basic steps. If a mistake is made or the student is unsure about next step they are directed to tutorials that explain the concepts. Choices made along the way are analysed to provide diagnostics suggesting areas of weakness. Very difficult to explain, extremely time consuming to build but hopefully easy to use.
