In this question, all we have to do is solve this equation for v.
00:04
And how can we do that? begin by sending this term to the other side.
00:09
So now we have p divided by m0 is equal to v divided by the square root of 1 minus v divided by c squared.
00:18
Now send this term to the other side.
00:20
Then you get p divided by m 0 times the square root of 1 minus v divided by c squared is equal to v.
00:30
Then, as our next step, square both sides of this equation.
00:34
So you get p divided by m0 squared times 1 minus v divided by c squared is equal to v squared.
00:44
Then simplify the left hand side to the following.
00:48
P divided by m0 squared minus p divided by m0 squared times v squared divided by m0 squared times v squared divided by c squared is equal to v squared.
01:00
Send this term to the other side.
01:02
To get the following, p divided by m0 squared is equal to v squared plus p divided by m0 squared times v squared divided by c squared.
01:16
Now on the right hand side, you factor out the factor of b squared...
