Abody of mass 5.0 kg is suspended by a spring which stretches 10 cm when the mass is attached. it is then displaced downward an additional 5.0 cm and released. its position as a function of time is approximately what?

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 =

k = 490 N/m

and ω is

ω =

ω =

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

if you answer my question i will answer yours

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
