<h2>Answer:</h2>
The correct answer is option C which is, "empirical evidence that was collected during the experiment".
<h3>Explanation:</h3>
Empirical evidence are the observations and data values collected during the experiment by using the senses.
Like if your are experimenting involving a chemical reaction, the temperate or color changes during the reaction should be counted in the interpretation of the results.
Hence the correct option is C.

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'
use the equations provided it shouldn't he hard
Answer:
Force = 100N
