1. Into ihamba ngendilinga enejubane elingaguquki le-angular elingu-10 rad/s. Thola (a) Ijubane le-angular ngemva kwemizuzwana eyi-10 (b) Ukufuduka kwe-angular ngemva kwemizuzwana eyi-10.
Kwaziwa:
Isivinini se-angular (ω) = 10 rad/s
Kufunwa:
(a) Isivinini se-angular (ω) ngemva kwemizuzwana eyi-10.
(b) I-engeli (θ) ngemva kwemizuzwana eyi-10
Isixazululo:
(a) Isivinini se-angular (ω) ngemva kwemizuzwana emi-10
Into ejikelezayo efanayo ukuze ijubane le-angular lihlale linjalo, ama-rad angu-10/s.
(b) Ukufuduka kwe-Angular (θ)
Ijubane eliqondile le-angular elingu-10 radians/second lisho into ezungeze ama-radians ayi-10 ngomzuzwana. Ngemva kwemizuzwana eyi-10, into ezungeze ama-radians ayi-10 x 10 = ama-radians ayi-100.

2. Inhlayiya ihamba ngendilinga enejubane elingaguquki elingu-10 m/s. Irediyasi yendilinga = imitha eli-1. Thola (a) Ijubane lezinhlayiya ngemva kwemizuzwana emi-5 (b) Ukufuduka kwezinhlayiya ngemva kwemizuzwana emi-5 (c) Ukusheshisa kwe-Centripetal.
Kwaziwa:
Irediyasi yesiyingi (r) = 1 imitha
Isivinini sezinhlayiya (v) = 10 m/s
Isixazululo:
(a) Isivinini sezinhlayiya ngemva kwemizuzwana emi-5
Ukunyakaza kwento kusekuhambeni okujikelezayo okufanayo ukuze ijubane lihlale linjalo, 10 m/s.
(b) Ukufuduka kwezinhlayiya ngemva kwemizuzwana emi-5
Amamitha ayi-10 ngomzuzwana kusho njalo ngomzuzwana owodwa, ukufuduka kwezinhlayiya = amamitha ayi-10. Ngemva kwemizuzwana emi-5, ukufuduka kwezinhlayiya = amamitha ayi-5 x 10 = amamitha angama-50.
(c) Ukusheshisa kwe-centripetal (a r )
a r = v 2 / r = 10 2 / 1 = 100 / 1 = 100 m/s 2
3. Ibhola elinamathiselwe kolunye uhlangothi lwentambo, lizungezwe ngendilinga enobubanzi obungamamitha ama-2 ngesivinini esingaguquki esingu-60 rpm. Nquma (a) ubukhulu bejubane le-angular ngemva kwemizuzwana emi-2 (b) ukufuduka kwe-angular ngemva komzuzu o-1.
Kwaziwa:
Irediyasi yesiyingi (r) = amamitha ama-2
Isivinini se-angular (ω) = 60 rpm = 60 revolutions / 1 minute
= imijikelezo engama-60 / imizuzwana engama-60 = umjikelezo o-1 / isekhondi = ama-radian angu-2π / isekhondi
= 2(3.14) ama-radians / isekhondi = 6.28 ama-radians / isekhondi
Isixazululo:
(a) Isivinini se-angular (ω) ngemva kwemizuzwana emi-2
Ijubane le-angular aliguquki ngakho-ke ngemva kwemizuzwana emi-2, ijubane le-angular (ω) = 6.28 radians / second
(b) Ukufuduka kwe-Angular (θ)
Ijubane eliyindilinga = ukujikeleza oku-1/umzuzwana kusho ukuthi njalo ngomzuzwana owodwa, ibhola lithola ukujikeleza oku-1. Ngemva kwemizuzwana engama-60, ibhola lihamba ukujikeleza okungu-60.
Ijubane le-angular = 6.28 radians/second kusho ukuthi njalo ngomzuzwana owodwa, ibhola lihamba nge-engeli yama-radians angu-6.28. Ngemva kwemizuzwana engu-60, ibhola lihamba ngama-radians angu-376.8.

4. Isondo lebhayisikili lijikeleza ama-revolution angu-120 ngemizuzwana engu-60. Liyini ijubane le-angular?
Isixazululo:
(a) ukuphenduka ngomzuzu (rpm)
Ukuvukela okungu-120 / imizuzwana engu-60 = ukuvukela okungu-120 / umzuzu ongu-1 = ukuvukela okungu-120 / umzuzu = i-120 rpm
(b) amadigri ngomzuzwana ( o /s)
Uguquko olu-1 = 360 o , uguquko olu-120 = 43200 o
Ukujikeleza okungu-120 / imizuzwana engu-60 = (120)(360 o ) / imizuzwana engu-60 = 43200 o / imizuzwana engu-60 = 720 o / isekhondi
(c) ama-radian ngomzuzwana (i-rad/s)
Uguquko olu-1 = ama-radian angu-6.28
Ukujikeleza okungu-120 / imizuzwana engu-60 = (120)(6.28) ama-radian / imizuzwana engu-60 = ama-radian angu-753.6 / imizuzwana engu-60 = ama-radian angu-12.56/isekhondi.
