1. Chinhu chine denderedzwa risina chinhu (I = m R)2) inofamba ichikunguruka isina kutsvedza ndege yakakombama isina kunaka nespeed yekutanga ye10 m/s. Ndege yakatsamira ine angle yekukwira θ ine tan θ = 0.75. Kana gravitational acceleration g = 10 ms-2, ivo velocity yechinhu chacho yaderedzwa kusvika 5 ms-1 ipapo daro riri pa ndege yakatsamira chinhu chacho…
Zvinozivikanwa:
Nguva yeinertia ye silinda isina chinhu (I) = m R2
Kona yekukwirira = θ, kupi kusviba kweganda θ = 0.75 = 75/100 = opp / adj
chivi θ = opp / hyp = 75/125 = 3/5 = 0.6
Kuwedzera nekuda kwegiravhiti (g) = 10 m/s2
Kumhanya kwekutanga (v)o) = 10 m/s
Kumhanya kwekupedzisira (v)t) = 5 m/s
Zvaidiwa: mufambo 
Solution:
Cverenga kukwirira kwasvikwa nesirinda uchishandisa equation ye kuchengetedzwa kwesimba remakanika.
Kureba kwekutanga (ho) = 0 mamita
Kumhanya kwekutanga (v)o) = 10 m/s
Kumhanya kwekupedzisira (v)t) = 5 m/s
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2
Silinda inosvika kukwirira kwemamita 7.5.
Kureba kwakafambwa nesirinda:
Nhambwe inofambiswa nesirinda ndeye 12.5 mamita.
Mhinduro chaiyo ndeinoti A.
Tsananguro ye equation:
o = yekutanga, t = yekupedzisira, INI = michina simba, PE = simba rinogona kuwanikwa, KE = simba reinetic, m = uremu, g = kukurumidza nekuda kwegiravhiti, h = kureba, v = kumhanya kwakatwasuka, ω = angular velocity, I = nguva yekusaita basa, R = nharaunda yesirinji
2. Sirinda yakasimba (I = ½ m R2) ine huremu hwe3 kg inofamba ichikunguruka isina kutsvedza, denderedzwa rakakombama rine kona yekukwira θ ine sin θ = 0.6. Kana kukurumidza kwegiravhiti g = 10 ms-2 uye kumhanya kwekutanga kwechinhu chacho kuri 10 m/s, ipapo kureba kwendege yakatsamira inofambiswa nechinhu ndicho…
Zvinozivikanwa:
Nguva yekusashanda kwe silinda yakasimba (I) = ½ m R2
Huremu hwesirinda = 3 kg
Kumhanya kwekutanga (v)o) = 10 m/s
Kumhanya kwekupedzisira (v)t) = 0 m/s (chinhu chinomira)
Kona yekukwirira (θ) = θ, uko chivi θ = 0.6 = 6/10 = zvinopesana/hyp
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2
Zvaidiwa: Tkureba kwendege yakakotama inofamba nechinhu
Solution:
Verenga kukwirira kwasvikwa nesirinda uchishandisa equation yekuchengetedza simba remakanika.
Kureba kwekutanga (ho) = 0 mamita
Kumhanya kwekutanga (v)o) = 10 m/s
Kumhanya kwekupedzisira (v)t) = 0 m/s (chinhu chinomira)
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2
Silinda inosvika kukwirira kwemamita 7.5.
Kureba kwakafambwa nesirinda:
Nhambwe inofambwa necylinder iyi i12.5 metres.
3. Chinhu chine denderedzwa risina chinhu (I = m R)2) ne radius R, inofamba ichikunguruka isina kutsvedza ichikwira denderedzwa rakakombama rine kona ye α apo sin α = 0.8. Kana kukurumidza kwegiravhiti g = 10 ms-2 uye kumhanya kwekutanga ndeye 8 ms-1 ipapo kureba kwendege yakakotama kunosvikwa nechinhu chisati chamira ndiko…
Zvinozivikanwa:
Nguva yekusashanda kwe silinda yakasimba (I) = m R2
Kumhanya kwekutanga (v)o) = 8 m/s
Kumhanya kwekupedzisira (v)t) = 0 m/s (chinhu chinomira)
Kona yekukwira kwendege yakatsamira (θ) = θ, uko chivi θ = 0.8
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2
Zvaidiwa: Kufamba kure necylinder
Solution:
Verenga kukwirira kwasvikwa nesirinda uchishandisa equation yekuchengetedza simba remakanika.
Kureba kwekutanga (ho) = 0 mamita
Kumhanya kwekutanga (v)o) = 8 m/s
Kumhanya kwekupedzisira (v)t) = 0 m/s
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2
Silinda inosvika kukwirira kwemamita 6.4.
Kureba kwakafambwa nesirinda:
Nhambwe inofambwa necylinder iyi i8 metres.
