Answer:

1.) Momentum = 10 units

2.) Because of gravity

Explanation:

According to the Newton 3rd law of motion, we realise that in collision, momentum is always conserved.

So, if a ball is thrown upward with ten units of momentum initially, the “recoil” momentum of the earth will be approximately 10 units of momentum. We do not feel this because of the gravity.
