Answer: 1.8 s
Step-by-step explanation:
Given
The height of the spring mass system above the table is given by
![h(t)=6.85\cos (3.42t)+9](https://tex.z-dn.net/?f=h%28t%29%3D6.85%5Ccos%20%283.42t%29%2B9)
The mass is performing S.H.M with frequency ![\omega =3.42](https://tex.z-dn.net/?f=%5Comega%20%3D3.42)
and ![\omega T=2\pi](https://tex.z-dn.net/?f=%5Comega%20T%3D2%5Cpi)
![\therefore T=\dfrac{2\pi }{\omega}](https://tex.z-dn.net/?f=%5Ctherefore%20T%3D%5Cdfrac%7B2%5Cpi%20%7D%7B%5Comega%7D)
time when mass returns to its original position
![T=\dfrac{2\pi }{3.42}\\\\T=1.8\ s](https://tex.z-dn.net/?f=T%3D%5Cdfrac%7B2%5Cpi%20%7D%7B3.42%7D%5C%5C%5C%5CT%3D1.8%5C%20s)
Answer:
225 mg remain in Aldi bloodstream
Step-by-step explanation:
150mg of amoxicillin was given daily for 10 days equals 1,500
of the 1500-40% =600mg
600mg divided by 4 days = 225mg still in blood stream
