1/2 × 1/2×1/2 + 1/2×1/2+1/2 = 2/8=1/4
Answer:
oof i dont know math that well
Step-by-step explanation:
R = 230 m
v = 17 m/s
Formula: |Ac| = v^2 / r
Point A
|Ac| = v^2 / r = (17m/s)^2 / (230m) = 1.257 m/s^2
Components:
cos(25) = - [ x-component / |Ac| ] => x-component = -|Ac|*cos(25)
sin(25) = - [y-component / |Ac| ] => y-component = - |Ac|*sin(25)
x-component = - 1.256 * cos(25) m/s^2 = - 1.139 m/s^2
y-component = -1.256 * sin (25) m/s^2 = - 0.531 m/s^2
Point B
|Ac| = 1.256
x-component = - 1.256 cos(58) = - 0.666 m/s^2
y-component = + 1.256 sin(58) = + 1.065 m/s^2
<u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u> </u>√15 units
Step-by-step explanation:
Let (6,1) be (x^1,y^1) and (1,-9) be (x^2,y^2) .
As we know ,
Distance(D) = √(x^1-x^2) +(y^1-y^2)
Now,
D= √(x^1-x^2) +(y^1-y^2)
= √(6-1) +(1+9)
= √5+10
= √15 units
: Therefore the distance between (6,1) and (1,-9) is √15 units.
