8. A particle is displaced from the equilibrium position by a distance 1=1.0 cm and then
left alone. What is the distance that the particle covers till its oscillations die down, if
the logarithmic decrement is equal to λ = 0.020?
[Answer: s=2 m nearly]
A particle of mass 0.350 kg is attached to the 100-cm mark of a meterstick of mass 0.125 kg. The meterstick rotates on the surface of a frictionless, horizontal table with an angular speed of 2.00
rad/s.
