Matambudziko matatu nemhinduro nezve Speed equation
1. Mota inofamba ichienda kumaodzanyemba kwemamita zana muminiti imwe chete yobva yatendeukira kumabvazuva kwemamita zana nemakumi maviri mumaminitsi 0.5. Sarudza avhareji yekumhanya kwemota.
Anozivikanwa:
Nhambwe yese = mamita zana + mamita zana nemakumi maviri = mamita mazana maviri nemakumi maviri
Nguva yose = miniti imwe + maminitsi 0.5 = maminitsi 1.5 = masekondi makumi mapfumbamwe
Zvinodiwa: Avhareji yekumhanya
Solution:
Fomura yekumhanya
Avhareji yekumhanya = daro rese: nguva yese = mamita mazana maviri nemakumi maviri: masekonzi makumi mapfumbamwe = mamita maviri nehafu/sekondi
2. Chikepe chinofamba mumutsara wakatwasuka kwedaro remamita zana mushure memasekonzi gumi. Avhareji yekumhanya kwechikepe chii?
Anozivikanwa:
Kureba = mamita zana
Nguva = masekondi gumi
Zvinodiwa : Avhareji yekumhanya
Solution:
Fomura yekumhanya
Avhareji yekumhanya = mamita zana: masekondi gumi = mamita gumi pasekondi
3. Chidimbu chinofamba kubva panzvimbo O kuenda panzvimbo B mumasekonzi mana uye kubva paB kuenda kuA mumasekonzi makumi maviri. Sarudza avhareji yekumhanya kwezvidimbu.
Inozivikanwa:
Kureba kweOB = mamita mashanu
Kureba kweBA = mamita masere
Nguva yeOB = masekondi mana
Nguva yeBA = masekondi makumi maviri
Zvinodiwa: Avhareji yekumhanya kwezvikamu
Solution:
Fomura yekumhanya
Avhareji yekumhanya kwezvikamu = daro rese : nguva yese = (5 + 8): (4 + 20) = 13: 24 = 0.54 metres/sekondi
