Hello students, in this question, mass of three particles as well as velocity of three particle is given where velocity is in vector form.
00:26
Now we need to utilize this in order to find out momentum of the particle, kinetic energy, velocity as well as translational kinetic energy and kinetic energy relative to center of mass.
00:42
Now looking at this velocity, it is in the form of 9 i cap minus 5 j cap 13 k cap.
00:54
So similarly another two velocity also.
00:58
Now in order to find momentum, we use the formula m into v where mass of the particle, first particle is 2.
01:08
Regarding that, according to x -axis, y -axis and z -axis, we need to multiply velocity component.
01:16
For that, mass of the first particle 2 into velocity of first particle with x component plus mass of the second particle into x component of second particle plus mass of third particle into velocity component x component of third particle.
01:46
Similarly for y component and z component, we will do the same thing.
01:59
Now for z component, from this calculation, the velocity of the particles will be this one.
02:25
Now we need to find velocity.
02:35
Velocity is given by momentum of the particle divided by total mass of the system.
02:42
For that, we had already calculated momentum...
