Let us begin with the first question.
00:06
Here 4 balls are given, ball a, ball b, c and d.
00:12
Here first of all we need to calculate their momentum.
00:17
So the momentum can be determined using the expression p equals mb.
00:21
Where p is linear momentum, m is mass of the ball and v is their velocity.
00:26
So the case of ball a, we can calculate p -a as m -a into v -a.
00:31
Here n is given as 1 kilograms into 9 meter per second this is equals to 9 kilogram meter per second similarly p b equals n b b b this is equal to 1 .2 kilogram into 8 .5 meter per second this is equals 10 .2 kilogram meter per second p c equals n c into vc this is equal to 0 .0 bryce 0 .8 kilograms into 12 meter per second.
01:07
So this is equals to 9 .6 kilogram meter per second.
01:14
Pv equals md into bv.
01:20
This is equals to 5 kilograms into 2 meter per second.
01:25
Which is equals to 10 kilogram meter per second.
01:28
So these are the momenta of all these bowls.
01:33
So from these we can rank their momentum...
