Can you please just rewrite this equation so that it makes sense?
2 kg 9.81 m/sec^2 40 m = 784.8 kg-m^2/sec^2 = 784.8 N-m = 748.8 j

This is an equation that calculates potential energy and converts the value into its commercial unit.

Step-by-step explanation:

Step 1:

Given equation is 2 kg × 9.81 m/s² × 40 m. From the units, find the corresponding measurements. kg is the unit of mass (m), 9.81 m/s² is the acceleration due to gravity (g) and m is the unit of length or height (h).

This shows that this equation is to find potential energy. It is then converted into the commercial unit of energy (Joules).

⇒ Potential Energy = mgh = 2 kg × 9.81 m/s² × 40 m

                                            = 784.8 kg m²/s²

                                            = 784.8 N-m (Since unit of force, 1 N=kg m/s²)

                                            = 784.8 J (1 Newton-m = 1 Joule)

-2 is the right
