Answer:
Explanation:
In equilibrium , weight of mug is equal to restoring force .
mg = kx where m is mass of mug , k is spring constant and x is extension .
k / m = g / x = 9.8 ms⁻² / .025 m
= 392
frequency of oscillation n = ![\frac{1}{2\pi}\sqrt{\frac{k}{m} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%5Cpi%7D%5Csqrt%7B%5Cfrac%7Bk%7D%7Bm%7D%20%7D)
![n=\frac{1}{2\pi}\sqrt{392 }](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B1%7D%7B2%5Cpi%7D%5Csqrt%7B392%20%7D)
= 4.46 per second.
Scientists work with life and psyical and engineers are think they make
16km because she is 8km away and if she goes back it’s gonna be 8km more so it’s 16km
