4 Mehlala ea lebelo le tloaelehileng le lebelo le tloaelehileng
1. Koloi e tsamaea ka ho toba botjhabela ka limithara tse 100 ka metsotsoana e 4 ebe e tsamaea ka ho toba bophirima ka limithara tse 50 ka motsotsoana o le mong. lebelo le tloaelehileng dan tao lebelo le tloaelehileng mobile.
Puisano
Sebaka = limithara tse 100 + limithara tse 50 = limithara tse 150
Palo ea ho falla = limithara tse 100 - limithara tse 50 = limithara tse 50 'me tsela eo ho falla ho eang ka eona e lebile bochabela.
Kakaretso ea nako = metsotsoana e 4 + motsotsoana o le 1 = metsotsoana e 5.
Lebelo le tloaelehileng = sebaka sohle / nako yohle = limithara tse 150 / metsotsoana e 5 = limithara tse 30 ka motsotsoana.
Lebelo le tloaelehileng = ho falla / nako = limithara tse 50 / metsotsoana e 5 = limithara tse 10 / motsotsoana.
2. Seithuti se tsamaea limithara tse 4 ho ea bochabela ka motsotsoana o le mong ebe se retelehela leboea ka limithara tse 3 ka motsotsoana o le mong. Fumana lebelo le tloaelehileng le boholo ba lebelo le tloaelehileng.
Puisano
Tsela eo motsamao o tsamayang ka yona ke leboya-botjhabela (lehlakore la motsu o lamunu).
Kakaretso ea nako = motsotsoana o le mong + motsotsoana o le mong = metsotsoana e 'meli.
Lebelo le tloaelehileng = sebaka sohle / nako eohle = limithara tse 7 / metsotsoana e 2 = limithara tse 3,5/motsotsoana
Lebelo le tloaelehileng = ho falla / nako eohle = limithara tse 5 / metsotsoana e 2 = limithara tse 2,5 / motsotsoana
3. Sheba setšoantšo se ka tlase! Motho o potoloha tšimo e khutlonnetsepa. Bolelele = limithara tse 50, bophara = limithara tse 20. Kamora ho potoloha tšimo habeli, motho o khutlela boemong ba ho qala. Haeba nako e le pakeng tsa metsotsoana e 100, fumana lebelo le tloaelehileng le boholo ba lebelo le tloaelehileng.
Puisano
Moeli oa tšimo = 2 (limithara tse 50) + 2 (limithara tse 20) = limithara tse 100 + limithara tse 40 = limithara tse 140.
Tšimo e pota-potiloe ka makhetlo a 2 = 2 (limithara tse 140) = limithara tse 280.
Sebaka = limithara tse 280.
Ka mora ho potoloha tshimo, motho eo o ile a kgutlela boemong ba hae ba pele ka lebaka la yona. ho falla = limithara tse 0.
Lebelo le tloaelehileng = sebaka / nako = limithara tse 280 / metsotsoana e 100 = limithara tse 2,8 / motsotsoana.
Lebelo le tloaelehileng = ho falla / nako = 0 / metsotsoana e 100 = 0.
4. Tafole e ka tlase e fana ka tlhahisoleseding mabapi le leeto la ntho ho tloha boemong ba A ho ea ho F ho latela X-axis hammoho le nako e tlalehiloeng.
Lebelo le tloaelehileng la ntho ho tloha ho A ho isa ho D ke…
A. -2,47m/s
B. -1,00 m/s
C. 1,00 m/s
D. 1,23 m/s
E. 2,47 m/s
Puisano
Sebaka AB = 52-30 = limithara tse 22
Sebaka BC = 52-38 = limithara tse 14
Sebaka CD = 38-0 = limithara tse 38
Kakaretso ea sebaka = 22 + 14 + 38 = limithara tse 74
Kakaretso ea nako = metsotsoana e 30
Lebelo le tloaelehileng = limithara tse 74 / metsotsoana e 30 = 2,47 m/s
Karabo e nepahetseng ke E.
Lipotso mabapi le lebelo le tloaelehileng le lebelo le tloaelehileng
1. Koloi e tsamaea ka ho toba botjhabela ka limithara tse 80 ka metsotsoana e 10 ebe e tsamaea ka ho toba bophirima ka limithara tse 60 ka motsotsoana o le mong. lebelo le tloaelehileng dan tao lebelo le tloaelehileng mobile.
2. Seithuti se tsamaea limithara tse 8 ho ea bochabela ka motsotsoana o le mong ebe se retelehela leboea ka limithara tse 6 ka motsotsoana o le mong. Fumana lebelo le tloaelehileng le boholo ba lebelo le tloaelehileng.
3. Sheba setšoantšo se ka tlase! Motho o potoloha tšimo e khutlonnetsepa. Bolelele = limithara tse 100, bophara = limithara tse 50. Kamora ho potoloha tšimo ka makhetlo a mararo, motho o khutlela boemong ba ho qala. Haeba nako e le pakeng tsa metsotsoana e 100, fumana lebelo le tloaelehileng le boholo ba lebelo le tloaelehileng.
