Answer:
x(t) = 0.077cos(6.455t)
Explanation:
If the spring can be stretched 0.2 m by a force of 50 N, then the spring constant is:
k = 50 / 0.2 = 250 N/m
The equation of simple harmonic motion is as the following:
where
We also know that the initial velocity is 0.5 m/s, which is also the maximum speed at the equilibrium:
is the initial phase
Therefore, the position of the mass after t seconds is
x(t) = 0.077cos(6.455t)
Regardless of whether solar ever truly turns into a noteworthy vitality source here in England is dubious. Up to this point, the UK solar industry had been going from solidarity to quality — in 2016, power delivered from solar power outperformed coal control out of the blue.
There is absolutely enough sunlight in the UK (we get around 60 percent of the sunlight got at the equator) to make putting resources into solar advantageous – as has been exhibited by the development of enormous scale solar tasks in Cornwall and Lincolnshire.
Be that as it may, since the legislature cut its help for the solar industry in 2015, the UK has seen an emotional fall in the rate of take off of solar PV boards. This foolhardy move has additionally activated a large number of occupation misfortunes in the solar industry.
Greenpeace is requiring the English government to desperately audit its help for the solar industry, for the atmosphere and for the effect it has had on the development of clean vitality industry occupations in the UK.
