1. Chinhu chine denderedzwa risina chinhu (I = m R 2 ) chinotenderera chisina kutsvedza mudenga rakakombama rine kumhanya kwekutanga kwe10 m/s. Denga rakakombama rine kona yekukwira θ ine tan θ = 0.75. Kana kukurumidza kwegiravhiti g = 10 ms -2 , kumhanya kwechinhu kwaderedzwa kusvika 5 ms -1 saka daro riri padenga rakakombama rechinhu iri…
Zvinozivikanwa:
Nguva yekusashanda kwe silinda isina chinhu (I) = m R 2
Elevation angle = θ , apo tan θ = 0.75 = 75/100 = opp / adj
Chivi θ = opp / hyp = 75/125 = 3/5 = 0.6
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Kumhanya kwekutanga (v o ) = 10 m/s
Kumhanya kwekupedzisira (v t ) = 5 m/s
Zvaidiwa: mufambo 
Solution:
Verenga kukwirira kwasvikwa nesirinda uchishandisa equation yekuchengetedza simba remakanika.
Kureba kwekutanga (h o ) = 0 mamita
Kumhanya kwekutanga (v o ) = 10 m/s
Kumhanya kwekupedzisira (v t ) = 5 m/s
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Silinda inosvika kukwirira kwemamita 7.5.
Kureba kwakafambwa nesirinda:
Nhambwe inofambwa necylinder iyi i12.5 metres.
Mhinduro chaiyo ndeinoti A.
Tsananguro ye equation:
o = kutanga, t = yekupedzisira, ME = simba remakanika , PE = simba rinogona kuitika, KE = simba rekinetic , m = uremu , g = kukurumidza nekuda kwegiravhiti, h = kureba, v = kumhanya kwakatsetseka, ω = kumhanya kwekona , I = nguva yekusashanda, R = radius yesilinda
2. Silinda yakasimba (I = ½ m R 2 ) ine huremu hwe3 kg inofamba ichikunguruka isina kutsvedza ichikwira denderedzwa rakakombama rine kona yekukwira θ ine sin θ = 0.6. Kana kukurumidza kwegiravhiti g = 10 ms -2 uye kumhanya kwekutanga kwechinhu kuri 10 m/s, saka kureba kwedenderedzwa rakakombama rinofambwa nechinhu kuri…
Zvinozivikanwa:
Nguva yekusashanda kwe silinda yakasimba (I) = ½ m R 2
Huremu hwesirinda = 3 kg
Kumhanya kwekutanga (v o ) = 10 m/s
Kumhanya kwekupedzisira (v t ) = 0 m/s (chinhu chinomira)
Elevation angle ( θ ) = θ , apo chivi θ = 0.6 = 6/10 = opp/hyp
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2
Zvinodiwa: Hurefu hwendege yakakotama yaifambwa nechinhu
Solution:
Verenga kukwirira kwasvikwa nesirinda uchishandisa equation yekuchengetedza simba remakanika.
Kureba kwekutanga (h o ) = 0 mamita
Kumhanya kwekutanga (v o ) = 10 m/s
Kumhanya kwekupedzisira (v t ) = 0 m/s (chinhu chinomira)
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Silinda inosvika kukwirira kwemamita 7.5.
Kureba kwakafambwa nesirinda:
Nhambwe inofambwa necylinder iyi i12.5 metres.
3. Chinhu chine denderedzwa risina chinhu (I = m R2 ) chine radius R, chinotenderera chisingatsvedzerere kumusoro kwedenderedzwa rakakombama rine kona yeα apo sin α = 0.8. Kana kukurumidza kwegiravhiti g = 10 ms -2 uye kumhanya kwekutanga kuri 8 ms -1 saka kureba kwedenderedzwa rakakombama kunosvikwa nechinhu chisati chamira kuri…
Zvinozivikanwa:
Nguva yekusashanda kwe silinda yakasimba (I) = m R 2
Kumhanya kwekutanga (v o ) = 8 m/s
Kumhanya kwekupedzisira (v t ) = 0 m/s (chinhu chinomira)
Kukwidza kona yendege yakarerekera ( θ ) = θ , uko chivi θ = 0.8
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Kudiwa: Kureba kwakafambwa nesirinda
Solution:
Verenga kukwirira kwasvikwa nesirinda uchishandisa equation yekuchengetedza simba remakanika.
Kureba kwekutanga (h o ) = 0 mamita
Kumhanya kwekutanga (v o ) = 8 m/s
Kumhanya kwekupedzisira (v t ) = 0 m/s
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Silinda inosvika kukwirira kwemamita 6.4.
Kureba kwakafambwa nesirinda:
Nhambwe inofambwa necylinder iyi i8 metres.
