To solve this problem we must understand the relationship between kinetic energy and momentum.
00:06
Kinetic energy that is k -e is given by half mv square.
00:11
So this can be written as half m square v square upon m.
00:16
So now m square is nothing but potential, nothing but momentum represented by p.
00:23
So p square upon 2m.
00:25
So kate kinetic energy is related to potential energy, sorry, momentum by this formula.
00:34
Now moving to the first part.
00:37
In first part, the kinetic energy of both is given to be same.
00:40
That is kc is equal to k basketball kb.
00:44
The kinetic energy of both are same.
00:46
So we can write this as p square momentum of c upon mass of two mass of c is equal to momentum of b upon two mass of b...
