Sarudza nzvimbo yechinhu chiri kufamba nepfuti

Matambudziko akagadziriswa mukufamba kwezviratidziro - sarudza nzvimbo yechinhu

1. Muviri unosimudzwa mudenga nekona ye60^o to nzvimbo yakatwasuka ine kumhanya kwekutanga kwe12 m/s. Sarudza nzvimbo yechinhu mushure mekufamba kwesekondi imwe chete! Kukurumidza kwegiravhiti iri 10 m/s².

Zvinozivikanwa:

Angle (θ) = 60^o

Pakutanga velocity (v_o) = 12 m/s

Nguva yenguva (t) = sekondi imwe chete

Kukurumidza kwegiravhiti (g) = 10 m / s²

Zvaidiwa: Nzvimbo yechinhu mushure mekufamba kwesekondi imwe chete

Solution:

Chikamu chakatarwa chekukurumidza kwekutanga:

v_ox =v_o cos θ = (12 m/s)(cos 60^o) = (12 m/s)(0.5) = 6 m/s

Chikamu chakamira chekukurumidza kwekutanga:

v_oy =v_o chivi θ = (12 m/s)(chivi 60^o) = (12 m/s)(0.5√3= = 6√3 m / s

Nzvimbo yechinhu iri munzira yakatwasuka:

Zvinozivikanwa:

Chikamu chekukurumidza chakatarwa (v)_x) = 6 m/s

Nguva yenguva (t) = sekondi imwe chete

Zvaidiwa: nzvimbo yakatwasuka (x)

Solution:

Mamita matanhatu pasekondi zvinoreva kuti bhora rinofamba kusvika pamamita matanhatu pasekondi imwe chete. Kureba kwebhora mushure mekufamba kwesekondi imwe chete mamita matanhatu. Saka nzvimbo yebhora munzira yakatwasuka mamita matanhatu.

Nzvimbo yechinhu panzvimbo yakatwasuka:

Sarudza nzira iri kumusoro seyakanaka uye nzira iri pasi seyakaipa.

Zvinozivikanwa:

Kumhanya kwekutanga (v)_o) = 6√3 m/s (zvakanaka zvichikwira)

Nguva yenguva (t) = sekondi imwe chete

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

Zvaidiwa: kureba mushure mekufamba kwesekondi imwe

Solution:

h = v_o t + 1/2 gt² = (6√3(1) + 1/2 (-10)(1)²) = 6√3 + (-5)(1) = 6√3 – 5 = 6(1.7) – 5 = 10.2 – 5 = 5.2 mamita.

Nzvimbo yechinhu mushure mekufamba kwesekondi imwe chete:

Kufamba kwakatambanuka (x) = mamita matanhatu

Kufamba kwakamira (y) = 5.2 metres

2. Muviri unosimudzwa mudenga nekona ye30^o to nzvimbo yakatwasuka kubva pachivako chakareba mamita makumi maviri. Kumhanya kwayo kwekutanga i50 m/s. Verenga kusimuka kwakamira mushure mekunge muviri wafamba kwesekondi imwe chete! Kukurumidza kwegiravhiti i10 m/s².

Zvinozivikanwa:

Angle (θ) = 30^o

Kureba kwekutanga (h)_o) = mamita makumi matanhatu

Kumhanya kwekutanga (v)_o) = 50 m / s

Nguva yenguva (t) = sekondi imwe chete

Kukurumidza kwegiravhiti (g) = 10 m / s²

Zvaidiwa: Urefu (h)

Solution:

Chikamu chakamira chekukurumidza kwekutanga:

v_oy =v_o chivi θ = (50 m/s)(chivi 30^o) = (50 m/s)(0.5) = 25 m / s

Hurefu:

Sarudza nzira iri kumusoro seyakanaka uye nzira iri pasi seyakaipa.

Zvinozivikanwa:

Kumhanya kwekutanga (v)_o) = 25 m/s (zvakanaka zvichikwira)

Nguva yenguva (t) = sekondi imwe chete

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

Zvaidiwa: Urefu (h)

Solution:

h = v_o t + 1/2 gt² = (25)(1) + 1/2 (-10)(1)²) = 25 + (-5)(1) = 25 – 5 = mamita makumi maviri.

Kureba kwemuviri mushure mekufamba kwesekondi imwe chete kuri mamita makumi maviri pamusoro penzvimbo iyo muviri uri. inofungidzirwa kana kuti mamita makumi mana pamusoro pevhu.

3. Bhora diki rakatambanudzwa rakatwasuka nespeed yekutanga v_o = 10 m/s kubva pachivako chakareba mamita gumi. Verenga bhora richifamba mushure mekufamba kwesekondi imwe cheteKukurumidza kwegiravhiti 10 m/s²

Zvinozivikanwa:

Kureba kwekutanga (h) = mamita gumi

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

Nguva yenguva (t) = sekondi imwe chete

Kukurumidza kwegiravhiti (g) = 10 m/s²

Kuda: Nzvimbo yebhora mushure mekufamba kwesekondi imwe chete!

Solution:

Kutamiswa kwakatwasuka:

Zvinozivikanwa:

Chikamu chekukurumidza chakatarwa (v)_x) = 10 m/s

Nguva yenguva (t) = sekondi imwe chete

Kuda: Nzvimbo yechinhu chacho

Solution:

Mamita gumi pasekondi zvinoreva kuti chinhu chinofamba kusvika pamamita gumi pasekondi imwe chete. Displacement Mushure mekufamba kwesekondi imwe chete, makiromita gumi. Saka kufamba kwakatwasuka kwakadzikama mamita gumi.

Kutamiswa kwakamira:

Yakaverengerwa se kufamba kwemahara kwekudonha.

Zvinozivikanwa:

Nguva yenguva (t) = sekondi imwe chete

Kukurumidza kwegiravhiti (g) = 10 m/s²

Zvaidiwa: Kureba mushure mekufamba kwesekondi imwe (h)

Solution:

h = 1/2 gt² = 1/2 (10)(1)²) = (5)(1) = mamita mashanu.

Mushure mesekondi imwe chete, chinhu chinodonha kusvika pamamita mashanu. Kureba pamusoro pepasi = mamita gumi - mamita mashanu = mamita mashanu.

Nzvimbo yechinhu mushure mekufamba kwesekondi imwe:

Nzvimbo yechinhu chacho pa yakachinjika nzira (x) = mamita gumi

Nzvimbo yechinhu chacho padivi rakamira (y) = mamita mashanu
