If the work done to stretch a spring by 4.0 cm is 6.0 J, what is the spring constant?
A) 300 N/m
B) 3000 N/m
C) 3500 N/m
D) 7500 N/m
E) 6000 N/m

The formula for the work done in stretching a spring is:

W = (1/2)kx^2

where W is the work done, k is the spring constant, and x is the distance stretched.

Plugging in the given values, we get:

6.0 J = (1/2)k(0.04 m)^2

Simplifying, we get:

k = 7500 N/m

Therefore, the answer is D) 7500 N/m.
