Dik :
ω = 4 rad/s
t = 5 sekon
Dit : θ = ....?
Peny :
θ = ω.t
θ = (4)(5)
θ = 20 radian.
No 7.
Dik :
t = 10 s
ω = 10 rad/s
Dit : θ = ...?
Peny :
θ = ω.t
θ = 10 x 10
θ = 100 rad
No 10.
Dik :
α = 2 rad/s²
ωo = 0
t = 5 sekon
Dit : ωt = ....?
Peny :
ωt = ωo + αt
ωt = 0 + (2)(5)
ωt = 10 rad/s
No 11.
Dik :
α = 2 rad/s²
ωo = 0
t = 5 sekon
Dit : θ = ....?
Peny :
θ = ωo.t + 1/2 αt²
θ = 0 x 5 + 1/2 (2)(5)²
θ = 0 + 1/2 (50)
θ = 25 rad
No 12.
Dik :
ω = 4 rad/s
t = 5 s
Dit : θ = ....?
Peny :
θ = ωt
θ = 4(5)
θ = 20 rad
