In this problem, we have been given four different balls.
00:04
This is ball a, ball b, ball c, and ball d.
00:08
So their masses and the speeds are indicated.
00:11
And we have to rank the momentum of these balls from maximum to the minimum values.
00:19
So we use this expression to compute the momentum, which is simple.
00:22
Just we multiply the mass with the speed.
00:26
So when we multiply mass with speed in a particular direction, we get the momentum for a as 9 kilograms meter per second.
00:34
For b we get it as 10 .2 kilograms meter per second.
00:38
And for c, we get it as 9 .6 kilograms meter per second.
00:43
And for d, we can get 10 kilograms meter per second.
00:47
So on rearranging them from maximum to the minimum value, we see that the momentum of ball b, that's greatest followed by ball d, followed by ball c, and finally ball a.
01:00
So that's that's the momentum.
01:00
That's the required order.
01:03
And next we have to also arrange, we have to rank the impulses which will be required to stop these balls and that also we have to rank from greatest to the least value...
