A child in about those 85.15 kg package out horizontally with a speed of 10 m/s the mass of the child is 27.2 kg in the mass of the ball is very 3.8 kg calculate the velocity of the ball immediately after assuming it was initially at rest
Nothing happened to make me change my opinion. So, immediately after assuming it was at rest, I still believed the ball was at rest. That is, its velocity was still zero in every direction.
