Good luck!
For the same generic reason that table salt doesn't taste or behave
like the corrosive sodium or the poisonous chlorine that it's made of.
The physical and chemical properties of compounds in general are
very different from the characteristics of any of their constituent

look up a speed calculator if you have more problems like this, it’ll save you time :)
Answer:
150J
Explanation:
Formula : <u>Work</u><u> </u><u>done</u>
Force x distance
work done = force x distance
Distance should be measured in meters
300÷100=3m
work done = 450 x 3
=150J
370.0 has exactly 4 significant figures.
