Answer:
Spring constant, k = 1.16 N/m
Explanation:
It is given that,
Mass of the air track, m = 0.2 kg
Time, t = 2.6 s
Let T is the time period of the spring. The expression for the time and spring constant is given by :
[tex]T=2\pi \sqrt{\dfrac{m}{k}}[/tex]
[tex]k=\dfrac{4\pi^2m}{T^2}[/tex]
[tex]k=\dfrac{4\pi^2\times 0.2}{(2.6)^2}[/tex]
k = 1.16 N/m
So, the spring’s force constant is 1.16 N/m. Hence, this is the required solution.
