A uniform light spring has unstretched length of 3.0 m. One of
its end is fixed to a wall. A particle of mass m = 20 g is glued to
the spring at a point 1.0 m away from its fixed end. The free end
of the spring is pulled away from the wall at a constant speed of 5
cm/s. Assume that the spring remains horizontal (i.e., neglect
gravity). Force constant of spring = 0.6 N/ cm. (a) With what speed
does the particle of mass m move? (b) Find the force applied by the
external agent pulling the spring at time 2.0 s after he started
pulling.
