Question 1174202: The number of centimeters, d, that a spring is compressed from its natural, uncompressed position is given by the formula d = square root 2W divded by k where W is the number of joules of work done to move the spring and k is the spring constant. Solve this equation for W. Use the result to determine the work needed to move a spring 2 centimeters if it has a spring constant of 0.4.

d=sqrt(2W/k)
d^2=2W/k
2W=kd^2
W=(1/2)kd^2
=(1/2)(0.4)*4
=0.8 j.
