Calculating Elongation of an Orange Spring

[brayrbob]

An orange spring has a spring constant of 14,000 g/s^2. How much should it stretch if a 200-g mass is attached from it?
I took the equation hanging mass * gravity=spring constant * elongation and turned it around for solving elongation
elongation = 200 * 980/14,000 = 14cm and I'm checking to see if this is the right answer.

Looks correct to me.

Your calculation is correct! The equation you used, elongation = hanging mass * gravity / spring constant, is the correct formula for calculating elongation of a spring. By plugging in the given values, you correctly determined that the orange spring should stretch by 14cm when a 200-g mass is attached to it. This means that the spring will increase in length by 14cm from its original unstretched position. Great job!
