Zvishandiso zveUnit - matambudziko nemhinduro
1. Chinhu chinofamba nespeed ye v = (2i − 1.5j) m/s. Chii chinonzi displacement yechinhu mushure memasekonzi mana?
Zvinozivikanwa:
Chikamu chakatarwa chevelocity (v x ) = 2 m/s
Chikamu chakamira chespeed (v y ) = 1.5 m/s
Nguva yepakati (t) = masekondi gumi nemashanu
Kudiwa: Kudzingwa
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. Kufamba kwenzvimbo iyi kwakakura sei?
Solution:
Zvinozivikanwa:
AF = AB – BF = AB – CD = 600 – 200 = 400 m
EF = DE – DF = DE – BC = 700 – 400 = 300 m
Kuwedzera mavector uchishandisa zvikamu - matambudziko nemhinduro
1. Maveki matatu sezvakaratidzwa mumufananidzo uri pazasi.
V1 = 30
V 2 = 30
V 3 = 40
Ndezvipi zviratidzo zvinobuda?
Zvinozivikanwa:
V 1 = 30, kona iri pakati peV 1 ne x axis = 30 o
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. Chii chinonzi avhareji yekumhanya uye avhareji yekumhanya?
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. Kumhanya kunokonzerwa negiravhiti i10 m/s2. Ndeipi nguva yekusvika pakukwirira kwakanyanya? Inozivikanwa : Kumhanya kwekutanga kwebara (vo) = 20 m/s Angle (θ) = 60oC … Verenga zvakawanda
Nheyo dzevatema - matambudziko nemhinduro
1. Mvura ine magiramu mazana maviri pa30°C yakasanganiswa nemvura ine magiramu zana pa90°C. Kupisa kwemvura chaiyo = 1 cal.gram −1 °C −1 . Sarudza tembiricha yekupedzisira yemusanganiswa!
Zvinozivikanwa:
Huremu hwemvura 2 (m1 ) = 200 magiramu
Kupisa kwemvura 1 (T 1 ) = 30 o C
Huremu hwemvura 2 (m2 ) = 100 magiramu
10 Dynamics Chinhu chakabatanidzwa netambo pamusoro pepulley Muchina weAtwood - Matambudziko neMhinduro
1. Bhokisi A rine huremu hwe5 kg, rakaiswa panzvimbo yakatsetseka yakatwasuka. Bhokisi B rine huremu hwe3 kg rakarembera pamucheto wetambo yakabatana nebhokisi A pamusoro pepulley. Kukurumidza kunokonzerwa negiravhiti ndeye 10 m/s 2. Chii chinonzi kukurumidza kwemabhokisi ese ari maviri?
Zvinozivikanwa:
Huremu hwebhuroko A (m)A) = 5 kg
Huremu hwebhuroko B (m B ) = 3 kg
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
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) Kukurumidza kwepakati pesimba (centripetal acceleration) kuri 32 ms -2
3) Simba repakati penyika i320 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 kukwira kwesimba nekuda kwegiravhiti kuri 10 ms -2 , kumhanya kwedombo kana rikarova pasi chii?
Zvinozivikanwa:
Kureba (h) = mamita mashanu
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Zvinodiwa: Kumhanya kwekupedzisira kwedombo parinorova pasi (v t )
