Sarudza kumhanya kwekupedzisira kwekufamba kweprojectile

1. Nhabvu inokandwa inobva pasi nekona θ = 30^o kusvika yakatwasuka ine kumhanya kwekutanga kwe14 m/s. Verenga kumhanya kwekupedzisira bhora risati rarova pasi.

Zvinozivikanwa:

Angle (θ= = 30^o

Kumhanya kwekutanga (v_o) = 14 m/s

Kukurumidza kwegiravhiti (g) = 10 m / s²

Zvaidiwa: Kumhanya kwekupedzisira bhora risati rarova pasi

Solution:

Chikamu chakatarwa chekukurumidza kwekutanga:

v_ox =v_o cos θ = (14 m/s)(cos 30^o) = (14 m/s)(0.5√3= = 7√3 m / s

Chikamu chakamira chekukurumidza kwekutanga:

v_oy =v_o chivi θ = (14 m/s)(chivi 30^o) = (14 m/s)(0.5) = 7 m/s

Kumhanya kwekupedzisira padivi rakamira

Sarudza nzira iri kumusoro seyakanaka uye nzira iri pasi seyakaipa.

Zvinozivikanwa:

Kumhanya kwekutanga (v)_o) = 7 m/s (yakanaka kumusoro)

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

Kureba (h) = 0 (chinhu chinodzokera panzvimbo yekutanga)

Zvaidiwa: Kumhanya kwekupedzisira (v)_t)

Solution:

v_t² =v_o² + 2 gh = 7² + 2(-10)(0) = 49 – 0 = 49

v_t = √49 = 7 m/s

Kumhanya kwekupedzisira padivi rakatwasuka

Kumhanya kwekutanga padivi rakatwasuka ndiko 7√3 m/s. Kumhanya hakuchinji saka kumhanya kwekupedzisira kwakafanana nekumhanya kwekutanga.

Kumhanya kwekupedzisira chinhu chisati charova pasi

2. Muviri unosimudzwa mudenga nekona ye30^o ine jira rakatwasuka kubva pachivako rine kukwirira kwemamita mashanu. Kumhanya kwaro kwekutanga i10 m/s. Verenga kumhanya kwekupedzisira chinhu chisati charova pasi! Kukurumidza kwegiravhiti i10 m/s².

Zvinozivikanwa:

Angle (θ= = 30^o

Kureba kwekutanga (h)_o) = mamita makumi matanhatu

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

Kukurumidza kwegiravhiti (g) = 10 m/s²

Zvaidiwa: Kumhanya kwekupedzisira

Solution:

Chikamu chakatarwa chekukurumidza kwekutanga:

v_ox =v_o cos θ = (10 m/s)(cos 30^o) = (10 m/s)(0.5√3= = 5√3 m / s

Chikamu chakamira chekukurumidza kwekutanga:

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

Kumhanya kwekupedzisira padivi rakamira

Zvinozivikanwa:

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

kumhanyisa regiravhiti (g) = –10 m / s² (kuderera kwakashata)

Kureba (h) = -5 m ((hazvina kunaka nekuti pasi riri pasi pekukwirira kwekutanga)

Zvaidiwa: Kumhanya kwekupedzisira (v)_t)

Solution:

v_t² =v_o² + 2 gh = 5² + 2(-10)(-5) = 25 + 100 = 125

v_t = √125 m/s

Kumhanya kwekupedzisira padivi rakatwasuka

Kumhanya kwekupedzisira padivi rakatwasuka ndiko 5√3 m/s.

Kumhanya kwekupedzisira

3. Bhora diki rakatambanudzwa rakatwasuka nespeed yekutanga v_o = 8 m/s kubva pachivako chakareba mamita gumi nemaviri. Verenga kumhanya kwekupedzisira bhora risati rarova pasiKukurumidza kwegiravhiti 10 m/s²

Zvinozivikanwa:

Kureba (h) = mamita mashanu

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

Kukurumidza kwegiravhiti (g) = 10 m/s²

Zvaidiwa: Kumhanya kwekupedzisira (v)_t)

Solution:

Chikamu chakatarwa chekukurumidza kwekutanga:

v_ox =v_o = 8 m/s

Chikamu chakamira chekukurumidza kwekutanga:

v_oy = 0 m/s

Kumhanya kwekupedzisira padivi rakamira

yakaverengerwa uchishandisa equation ye kufamba kwemahara kwekudonha.

Zvinozivikanwa:

Kukurumidza kwegiravhiti (g) = 10 m / s²

Kureba (h) = 12 m

Zvaidiwa: Kumhanya kwekupedzisira (v)_t)

Solution:

v_t² = 2 gh = 2(10)(12) = 240

v_t = √240 m/s

Kumhanya kwekupedzisira padivi rakatwasuka

Kumhanya kwekutanga munzira yakatwasuka i8 m/s. Kumhanya kwacho hakuchinji saka kumhanya kwekutanga kwakaenzana nekumhanya kwekupedzisira. Saka kumhanya kwekupedzisira munzira yakatwasuka i8 m/s.
