Answer:
<u>0.04kg</u>
Step-by-step explanation:
Kinetic energy Formula: eK=0.5×m×v²
to work out mass
we can rearrange the formula and make it:
~m=eK÷(0.5×v²)
now insert the missing digits into the formula:
m=200÷(0.5×100²)
work it out, and you get your answer
m=0.04kg
Hopefully this helped-have a good day)

Answer:
0.75c
Step-by-step explanation:
If we have an expression as:
a*x + b*x
We can see that both terms in the expression, a*x and b*x have an x, so we can call the x a common factor and we can write an equivalent expression as:
a*x + b*x = (a + b)*x
If we replace, for example, a by 2, b by 3 and x by 4, we can test the expression as:
2*4 + 3*4 = (2 + 3)*4
8 + 12 = (5)*4
20 = 20
Therefore, if we have the following expression:
c - 0.25*c
The expression that is equivalent is 0.75c and it is calculated as:
c - 0.25*c = (1 - 0.25)*c
c - 0.25*c = 0.75*c
