Given :
The pink car has a velocity of 4.4 m/s to the right while the blue car has a velocity of 6.8 m/s to the left.
To Find :
If the two cars crashed and stuck together, what would their combined momentum be afterwards and what direction would they be moving.
Solution :
Let, combined velocity of the car is v.
Also, let us assume that mass of both the cars are equal and it is m.
By conservation of momentum :
Initial momentum = Final momentum
m( 6.8 ) - m( 4.4 ) = 2mv
2mv =2.4m
v = 1.2 m/s
Therefore, the velocity of combined car after crash is 1.2 m/s .
There are organelles in the plant cell that the animal cell does not have. Plant cells have rigid cell walls and animal cells have flexible cell membrane. Plant cells contains chloroplasts, which is something animal cells don't have. Also, large, liquid filled vacuoles can only be found in plant cells, and they can occupy up to 90% of a cell's volume. By looking at the cell and see if they have any of these characteristics determines if it is plant cell or animal cell.
hope this helps.

I’m not too sure but maybe C?
