Answer:
20%
Step-by-step explanation:
4/5=.80
1-.80=.20
.20=20%
(x1, y1) (x2, y2)
(-4, 5) (-1, 1)
x2-x1
-1 - -4
-1+4
3
y2-y1
1- -4
1+4
5
answer : (3,5)
I believe this is right, hope this helps!
R = 25 cm = 0.25 m
α = 2.00 rad /s²
T(heta) = 4 π
ω = T(heta)/ t
ω = α t
α t = 4 π / t
t ² = 2 π
t = √ ( 2π ) = 2.5 s
ω = α t = 2 · 2.5 = 5 rad/s
v = ω r = 5 · 0.25 = 1.25 m/s
(1) a (rad) = ω² r = 25 · 0.25 = 6.25 m/s²
(2) a (rad) = v² / r = ( 1.25 )² / 0.25 = 0.15625 / 0.25 = 6.25 m/s²
