1. Into eyisilinda engenalutho (I = m R 2 ) iyahamba iyogingqika ngaphandle kokushelela phezulu endizeni ethambekele emangelengeleni ngesivinini sokuqala esingu-10 m/s. Indizeni ethambekele ine-engeli yokuphakama engu-θ ene-tan θ = 0.75. Uma ukusheshisa okudonsela phansi okungu-g = 10 ms -2 , ijubane lento lincishiswa libe ngu-5 ms -1 khona-ke ibanga endizeni ethambekele lento lingu…
Kwaziwa:
Isikhathi sokungahlali kahle kwesilinda esingenalutho (I) = m R 2
I-engeli yokuphakama = θ , lapho i-tan θ = 0.75 = 75/100 = opp / adj
Isono θ = opp / hyp = 75/125 = 3/5 = 0.6
Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s 2
Ijubane lokuqala (v o ) = 10 m/s
Ijubane lokugcina (v t ) = 5 m/s
Kufunwa: ibanga 
Isixazululo:
Cbala ukuphakama okufinyelelwe yi-cylinder usebenzisa i-equation ye- ukulondolozwa kwamandla okusebenza ngomshini.
Ukuphakama kokuqala (ho) = 0 amamitha
Ijubane lokuqala (v)o) = 10 m/s
Ijubane lokugcina (v)t) = 5 m/s
Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s2
Isilinda sifinyelela ukuphakama kwamamitha angu-7.5.
Ibanga elihanjwe ngesilinda:
Ibanga elihanjwa yi-cylinder liyi 12.5 amamitha.
Impendulo eyiyo ngu-A.
Incazelo yesibalo:
o = isiqalo, t = okokugcina, ME = amandla emishini, I-PE = amandla angase abe khona, i-KE = amandla kinetic, m = Mass, g = ukusheshisa ngenxa yamandla adonsela phansi, h = ukuphakama, v = ijubane eliqondile, ω = velocity angular, I = umzuzu wokungakhathali, R = irediyasi yesilinda
2. Isilinda esiqinile (I = ½ m R2) enesisindo esingama-3 kg iyahamba iyogingqa ngaphandle kokushelela phezulu indiza ethambekele emangelengeleni ene-elevation θ ene-sin θ = 0.6. Uma ukusheshisa kwamandla adonsela phansi g = 10 ms-2 futhi ijubane lokuqala lento lingu-10 m/s, bese ubude bendiza ethambekele ehanjwe yinto bungu…
Kwaziwa:
Isikhathi sokungabi namandla kwesilinda esiqinile (I) = ½ m R2
Isisindo sesilinda = 3 kg
Ijubane lokuqala (v o ) = 10 m/s
Ijubane lokugcina (v)t) = 0 m/s (ukuyeka kwezinto)
I-engeli yokuphakama (θ) = θ, lapho isono θ = 0.6 = 6/10 = opp/hyp
Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s2
Kufunwa: Tubude bendiza ethambekele ehanjwe yinto
Isixazululo:
Bala ukuphakama okufinyelelwe yi-cylinder usebenzisa i-equation yokonga amandla omshini.
Ukuphakama kokuqala (ho) = 0 amamitha
Ijubane lokuqala (v)o) = 10 m/s
Ijubane lokugcina (v)t) = 0 m/s (ukuyeka kwezinto)
Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s2
Isilinda sifinyelela ukuphakama kwamamitha angu-7.5.
Ibanga elihanjwe ngesilinda:
Ibanga elihanjwa yi-cylinder lingamamitha ayi-12.5.
3. Into eyisilinda engenalutho (I = m R2) nge-radius R, iyahamba iyogingqika ngaphandle kokushelela phezulu endizeni ethambekele emangelengeleni ene-engeli ka-α lapho i-sin α = 0.8. Uma ukusheshisa kwamandla adonsela phansi g = 10 ms-2 futhi ijubane lokuqala lingu-8 ms-1 bese ubude bendawo ethambekele efinyelelwe yinto ngaphambi kokuba ime bungu…
Kwaziwa:
Isikhathi sokungabi namandla kwesilinda esiqinile (I) = m R2
Ijubane lokuqala (v o ) = 8 m/s
Ijubane lokugcina (v)t) = 0 m/s (ukuyeka kwezinto)
I-engeli yokuphakama kwendiza ethambekele (θ) = θ, lapho isono θ = 0.8
Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s 2
Kufunwa: Ibanga elihanjwe ngesilinda
Isixazululo:
Bala ukuphakama okufinyelelwe yi-cylinder usebenzisa i-equation yokonga amandla omshini.
Ukuphakama kokuqala (ho) = 0 amamitha
Ijubane lokuqala (v)o) = 8 m/s
Ijubane lokugcina (v)t) = 0 m/s
Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s2
Isilinda sifinyelela ukuphakama kwamamitha angu-6.4.
Ibanga elihanjwe ngesilinda:
Ibanga elihanjwa yi-cylinder lingamamitha ayi-8.
