This is chapter 37, problem number 32.
00:03
We're given the speed of a particle that is rolling really fast.
00:09
0 .999 times the speed of light.
00:11
We're asked to calculate the relativistic momentum of this particle.
00:16
As you know, it's going to be gamma factor times the mess at rest times the speed of the particle is going to give us the relativistic momentum, where we have the lower inspector to.
00:30
To be 1 over square of 1 minus the speed of the particle squared divided by the speed of light square.
00:37
So if we plug this back in that equation, it's going to be 1 over square root of 1 minus v squared over c squared times m not times v.
00:50
So let's plug in for v because v is given to us as this.
00:54
If you do that, 1 over square of 1 minus 0 .999 times c, squared over c squared times and not times .999 times c, right? so let's look at here.
01:15
This is going to be .999 squared times c squared, c's they're going to cancel out...
