Answer :

Potential energy (Ep) is equal to the mass (m) of the subject multiplied by the height (h) from sea level that its positioned multiplied by the earth acceleration (g).

Ep = mgh
In your case m = 70 kg, g = 9.8m/s^2 , h = 3m , all the units are in SI, so simple multiplication gives Ep = 2060 J or Nm^2

Answer:2058 joules

Explanation:

Mass(m)=70kg

Acceleration due to gravity(g)=9.8m/s^2

Height(h)=3m

potential energy=m x g x h

Potential energy=70 x 9.8 x 3

Potential energy=2058
