Answer: 2.0 m
Explanation: Potential energy is the energy possessed by a body by virtue of its position.
[tex]{\text {potential energy}}=m\times g\times h[/tex]
where m= mass of body=0.3 kg
g= acceleration due to gravity =[tex]9.8m/s^2[/tex]
h = height of body = ?
[tex]5.88kgm^2s^{-2}=0.3\times 9.8\times h[/tex] [tex](1J=1kgm^2s^{-2})[/tex]
[tex]h= 2m[/tex]
