Answer:
As stated, the momentum of the system is conserved during the collision (even the kinetic energy is not - some energy is lost to heat, deformation, etc)
M1 V1 = M2 V2 expresses momentum conservation
150 kg-m/s = (40 + X) kg-m/s
X = 110 kg-m/s is the new momentum of the front car
More specifically,
M1 V1 + M2 V2 = M1 V1' + M2 V2'
6x2=12m
6x18=108
12m+108
Simplified: m+9 bc 12/12 and 108/12
The answer to it is the letter A
Answer:
energy : the ability to cause change
work : is force x distance or when an object moves a distance due to a specific force (measured in units of newtons-meters)
potential energy : is stored energy
kinetic energy : is energy in motion
mechanicle energy : the energy of motion such as a moving vechile
thermal energy : total kinetic energy in moving partsticles, like in boiling water (energy of heat)
chemical : energy stored in chemical bonds, like in plants
electromagnetic : waves with electric and magnetic properties , such as light
nuclear energy : energy stored in the nuclear atoms

The appropriate answer is d. chemical transformation of non living matter. Scientists believe that life originated on earth when the conditions present led to the formation of chemicals that contain carbon, nitrogen and oxygen. These are the primary components of organic matter and consequently all living things. Inorganic matter in ancient oceans could have been transformed into amino acids by complex reactions involving extreme heat or lightening.
