Sarudza kukwirira kwakanyanya kwekufamba kweprojectile

Matambudziko akagadziriswa mukufamba kwezviratidziro - sarudza kukwirira kwakanyanya

1. Nhabvu inokandwa inobva pasi nekona θ = 60^o neyakatwasuka ine kumhanya kwekutanga kwe10 m/s. Verenga kukwirira kwakanyanya! Kukurumidza kwegiravhiti iri 10 m/s².

Zvinozivikanwa:

Angle (θ) = 60^o

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

Zvaidiwa: Kureba kwakanyanya (h)

Solution:

Chikamu chakamira chekukurumidza kwekutanga:

pasina 60^o =v_oy /v_o

v_oy =v_o pasina 60^o = (10)(chivi 60^o) = (10)(0.5√3= = 5√3 m / s

Sarudza nzira iri kumusoro seyakanaka uye nzira iri pasi seyakaipa.

Zvinozivikanwa:

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

Chikamu chakamira chekukurumidza kwekutanga (v)_oy) = +5√3 m / s (zvakanaka zvichikwira)

Kumhanya kwekupedzisira pakukwirira kwepamusoro (v)_ty= = 0

Zvaidiwa: Kureba kwakanyanya (h)

Solution:

v_t² =v_o² + 2 gh

0² = (5√3)² + 2 (-10) maawa

0 = 25(3) – maawa masere

0 = 75 – maawa masere

75 = 20 h

h = 75/20

h = mamita 3.75

Kureba kwakanyanya mamita 3.75.

2. Muviri unosimudzwa mudenga nekona ye30^o ine kukwirira kwemamita makumi maviri kubva pachivako. Kumhanya kwayo kwekutanga i4 m/s. Verenga kukwirira kwakanyanya! Kukurumidza kwegiravhiti i10 m/s².

Zvinozivikanwa:

Angle (θ) = 30^o

Kureba kwekutanga (h) = mamita makumi maviri

Kumhanya kwekutanga (v_o) = 4 m/s

Kukurumidza kwegiravhiti (g) = 10 m/s²

Zvaidiwa: Kureba kwakanyanya (h)

Solution:

Chikamu chakamira chekukurumidza kwekutanga:

pasina 30^o =v_oy /v_o

v_oy =v_o pasina 30^o = (4)(chivi 30^o) = (4)(0.5) = 2 m / s

Sarudza nzira iri kumusoro seyakanaka uye nzira iri pasi seyakaipa.

Zvinozivikanwa:

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

Chikamu chakamira chekukurumidza kwekutanga (v)_oy) = +2 m / s (zvakanaka zvichikwira)

Kumhanya kwekupedzisira pakukwirira kwakanyanya (v)_ty= = 0

Zvaidiwa: Kureba kwakanyanya

Solution:

Kureba kwakanyanya:

v_t² =v_o² + 2 gh

0² = 2² + 2 (-10) maawa

0 = 4 – maawa masere

4 = 20 h

h = 4/20

h = mamita 0.2

Kureba kwakanyanya i 0.2 metres + 20 metres = 20.2 metres.
