α(t) = t²/5 rad/s²
t = 10 s
ω(o) = 2 rad/s
Tanya:
ω = .....?
Jawab:
ω adalah integral dari α, shg:
ω
ω(t) = (t³/15) + c
untuk mencari konstanta c, masukkan ω(0) = 2 rad/s
ω(0) = ((0³)/15) + c
2 = 0 + c
c = 2
maka, ω(t) = (t³/15) + 2
lalu, masukkan t = 10s
ω(10) = ((10)³/15) + 2
ω(10) = (1000/15) + 2 = (1000/15) + (30/15)
ω(10) = 1030/15
ω(10) = 68,67 rad/s
