When studying a solar energy system, the units encountered are kg · s⁻¹(m · s⁻²)² . Simplify these units and include joules (see Exercise 71) and only positive exponents in the final result.

Data from Exercises 71

The metric unit of energy, the joule (J), can be expressed as kg · s⁻² · m² . Simplify these units and include newtons and only positive exponents in the final result.
