Answer:
In order to solve this, you would subtract 8 from both sides. 8 minus 8 cancels out and 50 minus 8 minus 42.
Now, the equation should read like 2v^2=42. You would then divide both sides by 2v^2. 2v^2 divided by itself by cancels out which would leave you with 42/2v^2.
To divide fractions you flip the second fractions and multiply.
9/18 divided by 3/6 becomes -> 9/18 x 6/3
<u>9 </u>x <u>6 </u>-> <u>54</u>
18 x 3-> 54
your answer would simplify to 1.
For this question you should know that:
2/3 = 8/12
and
3/4 = 9/12
so now you can say:
7/12 < 8/12 < 9/12
so:
7/12 < 2/3 < 3/4 :)))
i hope this is helpful

The answer is 173 (tried my best to show my work)
A ) v = v o + g t
h = v o * t + g t² /2
10 m = 9.81 m/s² * t² / 2
9.81 t² = 20
t² = 2.038
t = 1.4278 s
v = 0 + 9.81 * 1.4278
v = 14 m/s
b ) v o = 14 m/s
v = v o² + 2 a d
0 = 14² + 2 a * 2.9
196 = - 5.9 a
a = 196 : ( - 5.9 )
a = - 33.79 m/s² ( the magnitude of his acceleration while in water )
c ) The total amount of force exerted on the swimmer in water:
F = m * a = 65 kg * 33.76 m/s²
F = 2,196.55 N
