Answer:

Epot = 294300 [J]

Explanation:

Potential energy is defined as the product of mass by height by gravitational acceleration. The height is measured with respect to the reference level. At this reference level the potential energy is equal to zero.

[tex]E_{pot}=m*g*h\\[/tex]

where:

m = mass = 150 [kg]

g = gravity acceleration [m/s²]

h = elevation = 200 [m]

[tex]E_{pot}=150*9.81*200\\E_{pot}=294300 [J][/tex]
