1. The problem statement, all variables and given/known data What is the period of oscillations of a spring fixed to the ceiling at one end and set in motion by attaching a mass 10kg to the other end? The spring constant is 20 N/m. 2. Relevant equations I used equations found in my lab book for Simple Harmonic Motion. ω=√k/m Then I used the equation ω=2pi/T to solve for T 3. The attempt at a solution I used equations found in my lab book for Simple Harmonic Motion. First I found ω according to ω=√k/m ω=√20/10 ω=√2 ω=1.41 Then I used the equation ω=2pi/T to solve for T 1.41 = 2pi/T 1.41(T)=2pi T=2pi/1.41 T=4 I rounded T to only 1 significant figure, the same as the given mass and spring constant. I have a final answer (4) but I am not sure I did this problem correctly, and I am unsure of my algebra where I solved for T. Also, would it be rounded to 1 significant figure? Any insight would be great. Thanks!
