Traceroute program is used to find the network paths and round-trip delays between source host and destination host. Open your command prompt running on a Linux system and run the traceroute program at command prompt using the following command:
traceroute < destination – host address>
Example: traceroute www. cs. test. uni. edu
The output of traceroute program contains 6 columns.
1st column: the number of router along the path or route
2nd column: name of the router
3rd column: IP address of the router
4th column: round-trip delay (1st experiment)
5th column: round-trip delay (2nd experiment)
6th column: round-trip delay (3rd experiment)

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
