Aforce of 60 n is used to stretch two springs that are initially the same length. spring a has a spring constant of 4 n/m, and spring b has a spring constant of 5 n/m. how do the lengths of the springs compare? how do the lengths of the springs compare? a. spring b is 1 m longer than spring a because 5 – 4 = 1. b. spring a is the same length as spring b because 60 – 60 = 0. c. spring b is 60 m longer than spring a because 300 – 240 = 60. d. spring a is 3 m longer than spring b because 15 – 12 = 3. i don't need the answer the correct answer is d
