Answer:
position as a function of time is y = 0.05 × cos(9.9)t
Explanation:
given data
mass = 5 kg
length = 10 cm = 0.1 m
displaced = 5 cm
to find out
position as a function of time
solution
we will apply here equilibrium that is
mass × g = k × length
put here value and find k
k = ![\frac{5*9.8}{.01}](https://tex.z-dn.net/?f=%5Cfrac%7B5%2A9.8%7D%7B.01%7D)
k = 490 N/m
and ω is
ω = ![\sqrt{\frac{k}{m} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bk%7D%7Bm%7D%20%7D)
ω = ![\sqrt{\frac{490}{5} }](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B490%7D%7B5%7D%20%7D)
ω = 9.9
so here position w.r.t time is
y = 0.05 × cosωt
y = 0.05 × cos(9.9)t
so position as a function of time is y = 0.05 × cos(9.9)t
Answer:
over harvesting, pollution, introduction of invasive species such as new predators and food competitors
Explanation:
The main cause of mass extinction is Humans cause extinction of a species through overharvesting. The second main cause is pollution ., introduction of invasive species such as new predators and food competitors, habitat destruction, overhunting and other influences. Another very important cause of mass extinction is the unsustainable human population growth.
The five mass extinction events are
Ordovician Mass Extinction
Devonian Mass Extinction
Permian Mass Extinction
Triassic -Jurassic Mass Extinction
and Cretaceous -Tertiary (or the K-T) Mass Extinction.
B. Kinetic energy plus its potential energy.
C. Their strengths are added
