In lab, you performed an experiment with a spring to find the mass of an "unknown mass." If the spring constant is 8.82 N/m and the "unknown mass" caused a displacement of 16.6 cm, what is the mass of the "unknown mass" in kg?

Answer:

m = 0.15 kg

Step-by-step explanation:

The experiment should be the "unknown mass" free hanging vertically from the spring. With this configuration the sum of forces will be:

K*X - m*g = 0

Solving for m:


m=(K*X)/(g) =(8.82*0.166)/(9.8)

m=0.15kg
