Answer:
45 m above the ground
Explanation:
The formula for height is height = PEg/ mg (gravitational potential energy/ mass times g).
37,485/ (85 kg*9.8m/s^2)
37,485/ 833 = 45 m above the ground
The height of construction worker above the ground is of 45 m.
Given data:
The mass of construction worker is, m = 85 kg.
The gravitational potential energy stored in worker is, U = 37,485 J.
We know that the energy of any object by virtue of its position is known as gravitational potential energy. So, the expression for the gravitational potential energy of construction worker is,
U = mgh
here,
g is the gravitational acceleration and h is the height above the ground.
Solving as,
37485 = 85 × 9.8 × h
h = 45 m
Thus, we can conclude that the height of construction worker above the ground is of 45 m.
