Hello everyone we are going to understand this question here given in the question given mass of player mass of player m1 is equal to 90 kg mass of ball mass of ball m2 is equal to 1 kg speed of ball u is equal to 15 meter per second mass of second athlete, mass of second athlete that is represented m3, which is equal to 80 kg.

Final speed of athlete we have to find.
01:28
Final speed of athlete we have to find.
01:41
Let final speed of first athlete be v1.
01:46
Let final speed of first athlete be v1.
02:03
And final speed of second athlete v and final speed of second athlete v2.
02:32
Now for the first player applying the conservation of energy for athlete one for athlete one applying conservation of momentum applying conservation of conservation of momentum.
03:08
So we can write m1 u1 is equal to sorry m1 into v1 is equal to m1 into v1 is equal to m2 into u so we can write v1 is equal to m2 upon m1 into u.
03:35
Now substituting the value in this value of m2 is means mass of ball that is 1 kg value of mass of first athlete that is 90 kg and speed of ball that is 15 so after calculation we will get 1 .6 meter per second and again applying the conservation of momentum so we can write m2 into v2 is equal to m3 into v3 m2 v2 is equal to m3 v3.
04:30
Now we can write, sorry, it is v2.
04:40
Here, this is u.

It is given by basically i wrote it v2, that is v...
