Answer:
The period of oscillation of the spring T = 0.702 sec
Step-by-step explanation:
Mass = 0.5 kg
Spring constant k = 40
![(N)/(m)](https://img.qammunity.org/2021/formulas/engineering/college/9ohwhv31sxnbqx93lcojuyipdsd728uxf5.png)
Compression of spring = 0.35 m
Period of oscillation
![T = 2 \pi \sqrt{(m)/(k) }](https://img.qammunity.org/2021/formulas/physics/high-school/pmy49igsd254k62zx49c4pcpku85fsvtq6.png)
Put all the values in above equation
![T = 2 \pi \sqrt{(0.5)/(40) }](https://img.qammunity.org/2021/formulas/physics/high-school/741nfp59c8ueog1jgmf1hf8gcg8h91q71k.png)
T = 0.702 sec
This is the period of oscillation of the spring.
