Zvishandiso zveUnit - matambudziko nemhinduro
1. Chinhu chinofamba pa velocity ye v = (2i − 1.5j) m/s. Chii chinonzi kudzingiswa yechinhu chacho mushure memasekonzi mana?
Zvinozivikanwa:
Chikamu chakatambanudzwa chevelocity (v)x) = 2 m/s
Chikamu chakamira chevelocity (v)y) = 1.5 m/s
Nguva yepakati (t) = masekondi gumi nemashanu
Zvaidiwa: Displacement
Kubviswa kweVector - matambudziko nemhinduro
1. Munhu anofamba kubva panzvimbo A kuenda panzvimbo B, mamita 600 kuchamhembe; ozoenda panzvimbo C, mamita 400 kumadokero; ozoenda panzvimbo D, mamita 200 kuchamhembe; ozopedzisa panzvimbo E, mamita 700 kumabvazuva. Ukuru hwemugwagwa uyu hwakaita sei? kudzingiswa?
Solution:
Zvinozivikanwa:
AF = AB – BF = AB – CD = 600 – 200 = 400 m
EF = DE – DF = DE – BC = 700 – 400 = 300 m
Mifananidzo yekufamba kwakatwasuka - matambudziko nemhinduro
1. Kureba kwegirafu (yakatwasuka) zvichienderana nenguva (yakatwasuka) sezvakaratidzwa mumufananidzo uri pazasi. Chinhu chiri padivi chinoratidzwa nenhamba…
Solution:
Nhamba 3, inoratidzwa nemutsetse wakatwasuka.
Avhareji yekumhanya - matambudziko nemhinduro
1. Mumwe munhu anotenderera rectangle ine urefu hwemamita mazana mana nehupamhi hwemamita zana, kagumi nembiri muawa imwe chete. Ndezvipi zviri kumhanya kwepakati uye avhareji kumhanya?
Zvinozivikanwa:
Kureba kwerectangle = mamita mazana mana
Upamhi hwe rectangle = mamita zana
Kutenderera kwerectangle = (2 x 400 metres) + (2 x 100 metres) = 800 metres + 200 metres = 1000 metres
Kureba = 12 x 1000 metres = 12,000 metres = 12 kilometers
27 Kufamba kwepfuti - matambudziko nemhinduro 1. Bara rinopfurwa pakona θ = 60o nekumhanya kwe20 m/s. Kukurumidza kunokonzerwa negiravhiti i10 m/s2. Ndeipi nguva yekusvika pakukwirira kwakanyanya? Inozivikanwa : Kumhanya kwekutanga kwebara (vo) = 20 m/s Angle (θ) = 60oC … Read more
Nheyo dzevatema - matambudziko nemhinduro
1. Mvura ine magiramu 200 pa30°C yakasanganiswa nemvura ine magiramu 100 pa90°C. kupisa chaiko yemvura = 1 cal.gram-1° C-1Sarudza tembiricha yekupedzisira yemusanganiswa!
Zvinozivikanwa:
Misa yemvura 2 (m1) = magiramu 200
Tembiricha yemvura 1 (T)1= = 30oC
Huremu hwemvura 2 (m2) = magiramu 100
10 Dynamics Chinhu chakabatanidzwa netambo pamusoro pepulley Muchina weAtwood - Matambudziko neMhinduro
1. Bhuroko A rine uremu ye5 kg, yakaiswa panzvimbo yakatsetseka yakatwasuka. Bhokisi B rine huremu hwe3 kg rakarembera pamucheto wetambo yakabatana nebhokisi A pamusoro pepulley. Kuwedzera nekuda kwegiravhiti iri 10 m/s2Chii chinonzi kukurumidza yemabhuroko ese ari maviri?
Zvinozivikanwa:
Huremu hwebhuroko A (m)A) = 5 kg
Huremu hwebhuroko B (mB) = 3 kg
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2
Kufamba kwedenderedzwa - matambudziko nemhinduro
1. Chinhu chinorema 10 kg chinofamba mudenderedzwa nekumhanya kwakafanana kwe4 m/s. Kana radius yedenderedzwa iri 0.5 metres, saka:
1) Kuwanda kwemadenderedzwa i4/π Hz
2) The kukurumidza kwepakati i32 ms-2
3) The simba repakati iri 320 N
4) Nguva yacho i4π s.
Ndeapi mashoko echokwadi?
Kufamba kwemahara kwemwaka wechando - matambudziko nemhinduro
1. Dombo rinodonha zvakasununguka kubva pakakwirira kwemamita makumi mana nemashanu. Kana kukurumidza nekuda kwegiravhiti iri 10 ms-2, dombo rinomhanya zvakadii kana rikarova pasi?
Zvinozivikanwa:
Kureba (h) = mamita mashanu
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2
Zvaidiwa: Kumhanya kwekupedzisira kwedombo parinorova pasi (vt)
