Depends on the age of the child. A new born will be about 1/2-1/3 of the mass of a really nice bike. while someone starting school will have more mass than a fair amount of bikes.
The bike wheel. It wil have its mass concentrated out by the rim.
No. That would be a very light bicycle
A parked semi truck has no momentum. A moving bicycle does. If both the bike and the truck are moving at the same speed in the same direction, the truck will have more because it has more mass.
Force is directly proportional to mass. Therefore, even both the car and bicycle are being accelerated to the same velocity, accelerating a car would require more force since it has a greater mass.
No Meter is an unit of length, not mass.
As the child is a minor, it is the responsibility of the parents.
kilogram
A set of scales
1.37 kilos would just be enough for a rather light bicycle frame, without any parts stuck to it.
Pain or death for the child.
the dump truck has the lowest kinetic the bike has the greatest becase of their mass
more than 1 billion
