Asmall car traveling with 5,000 kgm/s hits a light truck that was at rest at a red light. after the collision the small car bounces backwards with a momentum of 3,000 kgm/s. what would the momentum of the truck be after the collision?

8000

Explanation:

cause in the problem we dont have any ext Forces we know that the momentum of system is constant.

Fext=0

P1 + P2 = P1' + P2'

P2 = 0

5000 = -3000 + P2'

P2' = 5000+3000 = 8000

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
