As we know, that below sting is given by under root t by mu.
00:05
Here, t is the tension and mu is mass per unit length.
00:15
So both the strings v1 over v2 could be written as that would be under root t1 over t2 into m2 over m1.
00:27
Or we can say it would be, if you further simplify this, it would be t1 over t2.
00:37
V1 is what m1 over l1 so it would be m2 over m1 into 11 l1 all right this would be the velocity is so as we know what do we need to calculate we need to calculate both of them are 14 by 2 meter low so there is no point of using this it will be cancelled out mass is given and the tension is given mass is given and the tension is given a pulse is generated at one and the best things simultaneously once the fast first of all, which is the far end of its string.
01:14
After what additional time does the, we need to calculate the time, all right? so simply we need to calculate the velocities.
01:20
First of all, velocity given.
01:23
V1 would be under root.
01:26
T is the tension in 247 over 78 grams, 0 .078 kilograms into the length hell, alvards 14 .2 meter.
01:44
So this velocity would be under root 247 into 14 .2 divided by 0 .07.
01:55
So this is 212 .05 meter per second.
02:02
Similarly, b2 would be under root 194 over 0 .058 into 14 .2.
02:15
So this would be 217 .94 meter per second...
