Sarudza nguva yekufamba kweprojectile

Matambudziko akagadziriswa mukufamba kwezviratidziro - sarudza nguva inosara

1. Nhabvu inokandwa inobva pasi nekona θ = 30^o kusvika pakadzikama nekumhanya kwekutanga kwe10 m/s. Verenga nguva kuti usvike pakukwirira kwakanyanya! Kukurumidza kwegiravhiti iri 10 m/s².

Zvinozivikanwa:

Angle (θ) = 30^o

Kumhanya kwekutanga (v)_o) = 10 m/s

Kukurumidza kwegiravhiti (g) = 10 m/s²

Zvaidiwa: Nguva yekusvika pa kureba kwakanyanya

Solution:

Chikamu chakamira chekukurumidza kwekutanga:

v_oy =v_o chivi θ = (10 m/s)(chivi 30^o) = (10 m/s)(0.5) = 5 m / s

Nguva yekusvika pakukwirira kwepamusoro inotarwa ne kufamba kwakamira Sarudza nzira yekumusoro seyakanaka uye nzira yekudzikira seyakaipa.

Zvinozivikanwa:

Kumhanya kwekutanga (v)_o) = 5 m / s (zvakanaka zvichikwira)

Kukurumidza kwegiravhiti (g) = –10 m / s² (kuderera kwakashata)

Kumhanya kwekupedzisira pakukwirira kwakanyanya (v)_t= = 0

Zvaidiwa: nguva (t)

Solution:

v_t =v_o + gt

0 = 5 + (-10)t

0 = 5 – 10 t

5 = 10 t

t = 5/10 = 0.5 p

2. Muviri unosimudzwa mudenga nekona ye30^o to yakatambanuka ine kumhanya kwekutanga kwe30 m/s. Verenga nguva yekubhururuka! Kukurumidza kwegiravhiti i10 m/s².

Zvinozivikanwa:

Angle (θ) = 30^o

Kumhanya kwekutanga (v)_o) = 8 m/s

Kukurumidza kwegiravhiti (g) = 10 m / s²

Zvaidiwa: Nguva isati yasvika muviri usati warova pasi

Solution:

Chikamu chakamira chekukurumidza kwekutanga:

v_oy =v_o chivi θ = (8 m/s)(chivi 30^o) = (8 m/s)(0.5) = 4 m / s

Tinotanga taverenga nguva kuti tisvike pakakwirira tichishandisa equation yekufamba kwakamira.

Sarudza nzira iri kumusoro seyakanaka uye nzira iri pasi seyakaipa.

Zvinozivikanwa:

Kumhanya kwekutanga (v)_o) = 4 m / s (zvakanaka zvichikwira)

Kukurumidza kwegiravhiti (g) = –10 m / s² (kuderera kwakashata)

Kumhanya kwekupedzisira pakukwirira kwepamusoro (v)_t= = 0

Zvaidiwa: Nguva yepakati (t)

Solution:

v_t =v_o + gt

0 = 4 + (-10)t

0 = 4 – 10 t

4 = 10 t

t = 4/10 = 0,4 p

Nguva yekusvika pakukwirira kwakanyanya i 0.4 s.

Nguva iri mumhepo ndeye 2 x 0.4 s = 0.8 s.

3. Muviri unosimudzwa mudenga nekona ye30^o ine denga rakatwasuka kubva pachivako rine kukwirira kwemamita gumi. Kumhanya kwaro kwekutanga i40 m/s. Zvinotora nguva yakareba sei kuti muviri usvike pasi? Kukurumidza kwegiravhiti i10 m/s².

Zvinozivikanwa:

Angle (θ) = 30^o

Kureba kwekutanga (h)_o) = mamita makumi matanhatu

Kumhanya kwekutanga (v)_o) = 40 m/s

Kukurumidza kwegiravhiti (g) = 10 m / s²

Zvaidiwa: Nguva iri mumhepo (t)

Solution:

Chikamu chakamira chekukurumidza kwekutanga:

v_oy =v_o chivi θ = (40 m/s)(chivi 30^o) = (40 m/s)(0.5) = 20 m / s

Tinotanga taverenga nguva kuti tisvike pakakwirira tichishandisa equation yekufamba kwakamira.

Sarudza nzira iri kumusoro seyakanaka uye nzira iri pasi seyakaipa.

Zvinozivikanwa:

Kumhanya kwekutanga (v)_o) = 20 m / s (zvakanaka zvichikwira)

Kukurumidza kwegiravhiti (g) = –10 m / s² (kuderera kwakashata)

Kumhanya kwekupedzisira pakumhanya kwepamusoro (v)_t= = 0

Zvaidiwa: Nguva yepakati (t)

Solution:

v_t =v_o + gt

0 = 20 + (-10)t

0 = 20 – 10 t

20 = 10 t

t = 20/10 = masekondi maviri

Nguva iri mumhepo = 2 x 2 seconds = 4 seconds.

Chinhu chacho chiri pamusoro pevhu mamita gumi. Masekonzi mana ndiyo nguva inosvika panzvimbo yakaenzana nenzvimbo yekutanga. Bhora richiri kufamba richidzika pasi.

Nguva yekusvika pasi inoverengwa uchishandisa equation ye kufamba kwemahara kwekudonha. 

Zvinozivikanwa:

Kukurumidza kwegiravhiti (g) = 10 m / s²

Kureba (h) = mamita gumi

Zvaidiwa: Nguva yepakati (t)

Solution:

h = 1/2 gt²

10 = 1/2 (10) t²

10 = 5 t²

t² = 10/5 = 2

t = √2 = 1.4 masekondi

Nguva yepakati = 1.4 masekondi.

Nguva yese = masekondi mana + masekondi 1.4 = masekondi 5.4.

4. Bhora diki rakatambanudzwa rakatwasuka nespeed yekutanga v_o = 15 m/s kubva pachivako chakareba mamita mashanu. Verenga nguva mumhepoKukurumidza kwegiravhiti 10 m/s²

Zvinozivikanwa:

Kureba (h) = mamita gumi

Kumhanya kwekutanga (v)_o) = 15 m/s

Kukurumidza kwegiravhiti (g) = 10 m/s²

Kuda: Nguva iri mumhepo (t)

Solution:

Nguva iri mumhepo inoverengwa uchishandisa equation yekufamba kwakasununguka.

Zvinozivikanwa:

Kureba (h) = mamita gumi

Kukurumidza kwegiravhiti (g) = 10 m/s²

Zvaidiwa: Nguva yepakati (t)

Solution:

h = 1/2 gt²

5 = 1/2 (10) t²

5 = 5 t²

t² = 5/5 = 1

t = √1 = sekondi imwe
