Mass of the curl is 45 kgs.
00:07
Mass of the plant is 150 kgs.
00:14
And velocity of curl with respect to plant is 1 .505 m per second.
00:24
Now the momentum is conserved.
00:26
So that means the initial momentum is equal to final momentum.
00:34
But the whole system was in rest initially.
00:37
So initial momentum is zero.
00:40
So we have zero equal to p final.
00:45
And what is p final? p final is equal to mass of the curl multiplied by the velocity of curl with respect to ice plus mass of the plant multiplied by the velocity of plant with respect to ice.
01:08
Now we know that the relative velocity is given by velocity of curl with respect to plant is equal to velocity of curl with respect to ice minus velocity of plant with respect to ice.
01:28
So that gives us velocity of curl with respect to ice is equal to the velocity of curl with respect to plant plus velocity of plant with respect to ice...
