question 2 and 3 please

(2) Please discuss how to read out the spring constant k from the graph of data obtained in the two experiments below. (You will compare both methods in the lab.) W PHYS2125 Physics Laboratory I 2022S Kuei Sun The University of Texas at Dallas i. Student A varies force F exerted on a spring and measures its extension Ax, and plots the best-fit line of F vs Ax. [Hint: consider Eq. (1).] ii. Student B varies mass m attached on a spring and measures the angular frequency w of its simple harmonic oscillation, and plots the best-fit line of log w vs log m. [Hint: consider Eq. (4).] (3) From the previous question, Student B records the experimental data in the table below. m (kg) 0.221+0.0005 0.271+0.0005 0.321+0.0005 0.371+0.0005 0.421+0.0005 w (rad/s) 8.44+0.03 7.48+0.02 6.87+0.02 6.53+0.05 5.98+0.03 i. Use EXCEL to find the best-fit line of (log10 w) vs (log10 m). Record the slope, y-intercept, and R in Pre-lab. ii. From the best-fit line, find the spring constant k.(2) Please discuss how to read out the spring constant k. i. From the best-fit line of F vs Ax. [4] Answer: PHYS2125 Physics Laboratory I 20225 Kuei Sun The University of Texas at Dallas ii. From the best-fit line of log w vs log m. [4] Answer: (3) Analyze the best-fit line. (Express answers to 3 sig. figs. whenever applicable) i. (log10 W) =. x (log10 m) + ;RE = [6] ii. Spring constant k = N/m [1]
