Question

A spring force of spring constant k acts on a mass m particle at rest at position xo.show that after some time t it has the amplitude given by x(t)=x°Cos underroot k/m.t
.​

Answer 1

Answer:

(a) 1m(ω20+ω2)

(b) 1/(omega(omega_(0)^(2)-omega^(2))`

(c ) mω20−ω2

(d) mom20+ω2

Answer :

B

Explanation:

(b) Equation of displacement is given by x=Asin (ωt+ϕ) where A=f_(0)/(m(omega_(0)^(2)-omega^(2)))`.
