Answer:
490.5 J
Explanation:
m = Mass of rock = 10 kg
g = Acceleration due to gravity = 9.81 m/s²
h = Height from the ground = 5 m
The potential energy gives the energy that the body posseses due to its mass and height of the fall.
Potential energy is given by
[tex]U=mgh[/tex]
[tex]\Rightarrow U=10\times 9.81\times 5[/tex]
[tex]\Rightarrow U=490.5\ J[/tex]
The potential energy of the rock which is at the given height is 490.5 J
