A spring with 58 hangs vertically next to a ruler. The end of the spring is next to the 15- mark on the ruler. If a 2.0- mass is now attached to the end of the spring, where will the end of the spring line up with the ruler marks?
I used F=KX should it be mgy=kx? or mgy=1/2kx^2
The Attempt at a Solution
My solution was 32 centimeters and 34 centimeters and those were both wrong. Must use two sig figs.
