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?
a: spring b is 1 m longer than spring a because 5 โ 4 = 1.
b: spring a is the same length as spring b because 60 โ 60 = 0.
c: spring b is 60 m longer than spring a because 300 โ 240 = 60.
d: spring a is 3 m longer than spring b because 15 โ 12 = 3.
