Question

a bucket of unstretched springs (k=8 N/m) resting on the ground.Calculate the bucket's Mechanical Energy in [J}

Answer 1

Answer:

0 J

Explanation:

The mechanical energy of a spring is given by $0.5kx^{2}$ where k is spring constant and x is extension of spring. Since the spring is unstretched,  its extension is zero.

#Notice that the potential energy is 0.

-Substituting spring constant,  k with 8 and extension with zero then the mechanical energy will be

$0.5\times 8\times 0^{2}=0 J$
