Mavuto atatu ndi mayankho okhudza Speed equation
1. Galimoto imayenda kum'mwera kwa 100 m mu mphindi imodzi kenako n’kutembenukira kum’mawa 120 m mu mphindi 0.5. Dziwani liwiro lapakati la galimotoyo.
Zodziwika:
Mtunda wonse = mamita 100 + mamita 120 = mamita 220
Nthawi yonse = mphindi imodzi + mphindi 0.5 = mphindi 1.5 = masekondi 90
Kufunidwa: Liwiro lapakati
yankho;
Fomula ya liwiro
Liwiro lapakati = mtunda wonse: nthawi yonse = mamita 220: masekondi 90 = mamita 2.4/sekondi
2. Boti loyenda molunjika kwa mtunda wa mamita 100 patatha masekondi 10. Kodi liwiro lapakati la botilo ndi lotani?
Zodziwika:
Mtunda = mamita 100
Nthawi = masekondi 10
Akufunika : Liwiro lapakati
yankho;
Fomula ya liwiro
Liwiro lapakati = mamita 100: masekondi 10 = mamita 10/sekondi
3. Tinthu tating'onoting'ono timasuntha kuchoka pa mfundo O kupita pa mfundo B mu masekondi 4 ndipo kuchokera pa B kupita pa A mu masekondi 20. Dziwani liwiro lapakati la tinthu tating'onoting'ono.
Amadziwika:
Mtunda wa OB = mamita 5
Mtunda wa BA = mamita 8
Nthawi ya OB = masekondi 4
Nthawi ya BA = masekondi 20
Kufunidwa: Liwiro lapakati la tinthu tating'onoting'ono
yankho;
Fomula ya liwiro
Liwiro lapakati la tinthu tating'onoting'ono = mtunda wonse: nthawi yonse = (5 + 8): (4 + 20) = 13: 24 = 0.54 mamita/sekondi
