Physics question, will mark brainliest ! a construction truck collides with the back of a subcompact car. which one has the larger change of velocity during the collision?

the huge truck has a larger change in velocity
they have the same change of velocity
neither one changes its velocity
the small car has a larger change in velocity.

explain the answer.

The small car has a larger change in velocity.

Explanation:

The largest change of velocity will be in the smallest mass car, this happens because in the collision the change is in the kinetic energy; k = (1/2)m*v^2

where m is the mass and v is the velocity

so for a fixed change of kinetic energy k (that depends on the collision), if m is big, the change in v must be small, and if m decreases, v must increase.

from this, we can see that the vehicle with a smaller mass will be the biggest change in the velocity.

The correct option is:

The small car has a larger change in velocity.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
