Kushandiswa kwekuchengetedza simba remakanika pakufamba kwezviratidziro - matambudziko nemhinduro

1. Nhabvu inokandwa inobva pasi nekona θ = 30^o nekumhanya kwekutanga kwe10 m/s. Mabhora uremu = 0.1 makirogiramu. Kuwedzera nekuda kwegiravhiti is 10 m / s². Sarudza (a) Iyo simba regiravhiti panzvimbo yakakwirira (b) Nzvimbo yepamusoro kana kuti kukwirira kwakanyanya

Zvinozivikanwa:

Huremu (m) = 0.1 kg

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

Angle = 30^o

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s²

Solution:

(a) Simba regiravhiti

Verenga chikamu chakarara (v)_ox) uye chikamu chakamira (v_oy) yekumhanya kwekutanga.

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

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

Simba rekutanga remakanika

The kwokutanga michina simba (Ini_o) = simba reinetic (KUNA)

ME_o = KE = ½ mv_o² = ½ (0.1)(10)² = ½ (0.1)(100) = ½ (10) = 5 Joules

Simba rekupedzisira remakanika

Kinetic simba panzvimbo yepamusoro:

KE = ½ mv_ox² = ½ (0.1)(5√3)² = ½ (0.1)((25)(3)) = ½ (0.1)(75) = 3.75 Joules

Nheyo yekuchengetedza simba remakanika

Simba rekutanga remakanika (ME)_o) = simba rekupedzisira remakanika (ME)_t)

KE = PE + KE

5 = EP + 3.75

PE = 5 – 3.75 = 1.25 Joule

Simba regiravhiti rinogona kukweva panzvimbo yakakwirira i1.25 Joules.

(b) Nzvimbo yepamusoro-soro kana kuti kukwirira kwakanyanya

PE = mgh

1.25 = (0.1)(10) h

1.25 = awa

Kureba kwakanyanya i1.25 metres.

2. Bhora re 0.1-kg rakatambanudzwa rakatwasuka nespeed yekutanga v_o = 10 m/s kubva pachivako chine kukwirira kwemamita gumi. Kukurumidza kwesimba nekuda kwegiravhiti ndeye 10 m/s²Tsvaga simba rebhora rinofamba-famba kana richirova pasi.

Zvinozivikanwa:

Huremu (m) = 0.1 kg

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

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s²

Kuchinja kwehurefu (h) = 10 – 2 = 8 m

Kuda: simba rekinetic pamamita maviri pamusoro pevhu

Solution:

Simba regiravhiti (PE) = mgh = (0.1)(10)(10) = 10 Joules

Simba rekutanga rekinetic (KE) = ½ mv_o² = ½ (0.1)(10)² = ½ (0.1)(100) = ½ (10) = 5 Joules

Simba rekupedzisira rekinetic = simba rekutanga regiravhiti + simba rekutanga rekinetic = 10 + 5 = 15 Joules
