Understanding Forced Oscillations in a Stretched Wire

[buyuk_turkiye_ufo]

1- A wire 10.0 m long and having a mass of 100 g is stretched under a tension of 250 N. If two disturbances separeted in time by 0.030 s are generated one at each of the wire where will the distrubances meet?

2- Consider the forced oscillations. At t=0, the driving force
F(t)=F(0)[1.exp(-at)] is turned on. Find the displacement at any time. Assume that at t=0, the displacement is zero and initial velocitiy is V0

You need to make an attempt at the probem. Tell us what you tried to do.
