Answer:
P.E = 0.64 k joules
Step-by-step explanation:
Given data,
The mass of the block, m = 8 kg
The compression of the spring, x = 0.8 m
The spring constant is given by 'k'
When a spring is compressed to a length x, the energy stored in the spring is purely potential.
The potential energy stored in the compressed spring is given by the formula,
P.E = kx²
Substituting the given values,
P.E = k x 0.8²
P.E = 0.64 k joules
Where 'k' is the spring constant of the given spring.
