Stunt car A and stunt car B are identical cars with the same mass of 35.9 kg. They are both traveling at 37.1 m/s. Stunt car A crashes into a hard concrete wall, whereas stunt car B crashes into a big soft mattress. They both come to a complete stop after the impact. Stunt Car A experiences a over a of time. Stunt Car B experiences a over a of time. Because of the force experienced by Stunt Car A, it will sustain damage than Stunt Car B.

The possible answers are: short period, large force, more, long period, small force, less.

Stunt car A and stunt car B are identical cars with the same mass of 35.9 kg. They are both traveling at 37.1 m/s. Stunt car A crashes into a hard concrete wall, whereas stunt car B crashes into a big soft mattress. They both come to a complete stop after the impact.Stunt Car A experiences a LARGE FORCE over a SHORT PERIOD of time. Stunt Car B experiences a SMALL FORCE over a LONG PERIOD of time. Because of the force experienced by Stunt Car A, it will sustain MORE damage than Stunt Car B.

Explanation:

As we know that force is given as rate of change in momentum

so it is defined as

so here we know that both the cars are identical and both are moving with same speed so after coming to rest both the cars have same change in momentum

while Car A will experience more force because due to collision with concrete wall the time of collision is very small as compared to Car B

So Force on Car A is more than the force on Car B

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
