Calculate the elastic potential energy stored in a spring, spring constant of 0.15 N/m, when it is extended by 10 m.

elastic potential energy= force multiplied by extension

= 0.15 multiplied by 10 = 15

any one of the statements could be an accurate comparison. but the statement that would define the correct choice and seal the deal is not even on the list:

"the visibilities of vector-x and vector-y in the drawing provided with the question are identical and nonexistent."

i think the answer would be reserve.
