The height of the shelf is 20 m. The potential energy of an object is due to the position of a different part of the object.
What is potential energy ?
The potential energy of an object is due to the position of a different part of the object.
It can be given as
[tex]U = mgh[/tex]
Where,
[tex]m[/tex] - mass
[tex]g[/tex] - gravitational energy
[tex]h[/tex] - height
Put the values in the formula,
[tex]350 = 17 \times 9.8 \times h\\\\h = \dfrac {350} { 166.6}\\\\h = 2.10{ \rm \ or}\\\\h = 20 \rm m[/tex]
Therefore, the height of the shelf is 20 m.
