Kufamba pasi mukudonha kwakasununguka - matambudziko nemhinduro

Matambudziko Akagadziriswa muKufamba Kwemutsetse - Kufamba Kwepasi mukuwa kwakasununguka

1. Bhora rinokandwa rakamira pasi nekumhanya kwekutanga kwe10 m/s uye rinosvika pasi mumasekonzi maviri. Tsvaga kumhanya kwekupedzisira bhora risati rasvika pasi. Kukurumidza kwegiravhiti (g) = 10 m/s²Usafuratira kuramba mhepo.

Zvinozivikanwa:

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

Nguva yakapera (t) = masekondi maviri

Kukurumidza kwegiravhiti (g) = 10 m/s²

Kudiwa: Kumhanya kwekupedzisira (v)_t)

Solution:

Kukurumidza 10 m/s² zvinoreva kuwedzera kwekumhanya ne 10 m/s sekondi imwe neimwe. Mushure memasekonzi matatu, kumhanya = 30 m/s.

Kumhanya kwekupedzisira = 10 m/s + 20 m/s = 30 m/s.

Maequations eKinematic e kufamba nekumhanya nguva dzose, sezvakaratidzwa pazasi:

v_t =v_o + pa ………. 1

h = v_o t + ½ pa² …………. 2

v_t² =v_o² + 2 ah …………. 3

v_t =v_o + gt

v_t = 10 + (10)(2)

v_t = 10 + 20 = 30 m/s

Kumhanya kwekupedzisira = v_t = 30 m/s

2. Dombo rinokandwa pasi rakamira kubva pabhiriji nekumhanya kwekutanga kwe5 m/s uye rinosvika mumvura mumasekonzi maviri. Verenga kukwirira kwebhiriji.

Zvinozivikanwa:

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

Nguva yakapera (t) = masekondi maviri

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s²

Zvaidiwa: kukwirira kwebhiriji (h)

Solution:

h = v_o t + ½ gt²

h = (5)(2) + ½ (10)(2)²

h = 10 + (5)(4)

h = 10 + 20

h = mamita mashanu

3. Bhora rinokandwa rakamira pasi nekumhanya kwekutanga kwe10 m/s kubva pakukwirira kwemamita 80. Tsvaga (a) Nguva mumhepo (b) Kumhanya kwekupedzisira bhora risati rarova pasi.

Zvinozivikanwa:

kukwirira (h) = mamita makumi masere

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

Kukurumidza kwegiravhiti (g) = 10 m/s²

Zvaidiwa:

(a) Nguva (t)

(b) Kumhanya kwekupedzisira (v)_t)

Solution:

(a) Nguva (t)

Kumhanya kwekupedzisira:

v_t² =v_o² + 2 gh

v_t² = (10)² + 2(10)(80) = 100 + 1600 = 1700

v_t = 41 m/s

Nguva yepakati (t):

v_t =v_o + gt

41 = 10 + (10)(t)

41 - 10 = 10 t

31 = 10 t

t = 31 / 10 = masekondi maviri

(b) Kumhanya kwekupedzisira (v)_t) ?

v_t = 41 m/s
