The free fall speed of a falling body weighing 2 kg increased from 1 m / s to 4 m / s. List all correct statements.

The free fall speed of a falling body weighing 2 kg increased from 1 m / s to 4 m / s. List all correct statements. 1) the momentum of the body at the beginning of the fall is 2 kg m / s 2) the momentum at the end is 4 kg m / s 3) when the body falls the momentum of the system the body and the earth is conserved

1) Yes, according to the formula
p = m * V
The impulse will be equal to 2 kg * m / s
2) No, everything is according to the same formula
p = m * V
The answer will be equal to 8 kg * m / s
3) The momentum of the body that falls will transfer to the ground
