Answer:
1.44%
Explanation:
The potential energy of a spring is given by
The kinetic energy is
Now x = 12 A
Applying in the first equation
The percentage would be 14400%
at (makes more sense)
The percentage is 25 % of the kinetic energy
Because the light colors will only work on a dark background, as dark colors will only work on a light background.

Work is equal to the force exerted times the distance traveled. This can be expressed using the following formula:
W = F × D
Insert any known values into the formula above:
W = (70 N) × (9 m)
Simplify the right side of the equation:
W = 630 N·m
The work done is equal to 630 J.
I hope this helps!
