sophist, i am not stupid; the force of the car stopping that sends the child in the air has to affect the weight somehow

sophist is correct, but impolite.
The weight (mass, actually) of the child is 25 kg.
This is approximately 55 pounds, which explains another answer you received.
Actually weight should be expressed as a force. The force of gravity on 25 kg is 25 x 9.8 = 245 N.
That is the child's weight, 245 Newtons.
