To verify the calculations, the units are substituted into the equations below alongside the numbers. Which equation has to be incorrect?
- A$\text{force} = \dfrac{300\,\text{J}}{6\,\text{m}}$
- B$\text{power} = 6000\,\text{J} \times 20\,\text{s}$
- C$\text{time} = \dfrac{6\,\text{m}}{30\,\text{m s}^{-1}}$
- D$\text{velocity} = 4\,\text{m s}^{-2} \times 30\,\text{s}$
