Matla a bohareng a potolohang ka mokhoa o ts'oanang - mathata le litharollo

1. Bolo ea 0.1 - kg, e hoketsoeng qetellong ea thapo e rapameng, e potoloha ka selikalikoe sa radius ea 50 cm 'me lebelo la angular la bolo ke s 4 rad s -1 . Boholo ba matla a bohareng ke bofe?

Tse tsejoang:Matla a bohareng a motsamao o chitja o tšoanang - mathata le litharollo 1

Boima (m) = digrama tse 100 = 100/1000 kg = 1/10 kg = 0.1 kg

Lebelo la Angular ( ω) = 4 radians/se cond

Radius (r) = 50 cm = 50/100 m = 0.5 m

Ho batloa: Matla a bohareng

Tharollo:

Matla a bohareng ke matla a sa feleng a hlahisang ho potlaka ha bohareng :

∑ F = ma r

∑ F = mv 2 /r = m ω 2 r

∑ F = matla a letlooa = matla a bohareng , m = boima , v = lebelo , ω = lebelo la angular , r = radius

∑ F = m ω 2 r = (0.1)(4) 2 (0.5) = (0.1)(16)(0,5) = 0.8 Li-Newton

2. Bolo e potoloha ka ho lekana ka selikalikoe se rapameng. Haeba lebelo le fetoha ho ba le boleng ba pele bo fetang makgetlo a mane, boholo ba matla a bohareng ke bofe…..

Tse tsejoang:Matla a bohareng a motsamao o chitja o tšoanang - mathata le litharollo 2

Boima = m

Lebelo = v

Lebelo la pele = v o

Radius (r) = r

Ho batloa: Boholo ba matla a bohareng

Matla a bohareng a motsamao o chitja o tšoanang - mathata le litharollo 3

3. Sekotwana sa radius R se hlophisitswe ka tsela eo koloi e tsamayang ka lebelo la 12 ms –1 e ka kgonang ho thinya ka tsela e bolokehileng. Koefficient ya kgohlano e sa fetoheng pakeng tsa koloi le tsela = 0.4. Radius R ke eng . Ho potlaka ka lebaka la matla a khoheli ( g ) = 10 ms –2.

Tse tsejoang:

Lebelo (v) = 12 m/s

Koefficient ea khohlano e sa fetoheng ( μs ) = 0.4

Ho potlaka ka lebaka la matla a khoheli (g) = 10 m/s 2

Ho batloa: Radius (R)
