Kushandiswa kwekuchengetedza simba remakanika pakufamba kwakatwasuka mukudonha kwakasununguka - matambudziko nemhinduro

1. Munhu anokanda dombo re 1-kg mudenga ne 2 m/s akamira pamucheto pedombo kuitira kuti dombo ridonhe pasi pedombo riri pasi pe 40 metres. Chii chinonzi simba reinetic yematombo ari pamusoro pevhu mamita gumi? Kuwedzera nekuda kwegiravhiti g = 10 m/s².

Zvinozivikanwa:

Misa (m) = 1 kg

Kumhanya kwekutanga (v)_o) = 2 m/s

Kuchinja kwehurefu = 40 - 10 = mamita makumi matatu

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s²

Zvaidiwa: simba rekinetic rematombo pamamita gumi pamusoro pevhu

Solution:

Simba rekutanga remakanika

Simba rekutanga regiravhiti (EP) = mgh = (1)(10)(30) = 300 maJoules

Simba rekutanga rekinetic (KE) = ½ mv_o² = ½ (1)(2)² = ½ (4) = 2 maJoule

The kwokutanga michina simba = yekutanga simba regiravhiti + simba rekutanga rekinetic = 300 + 2 = 302 Joules.

Simba rekupedzisira remakanika

Simba rekupedzisira remakanika = simba rekupedzisira rekinetic = simba rekutanga regiravhiti + simba rekutanga rekinetic = 300 + 2 = 302 Joules.

2. Munhu anokanda chinhu chinorema 1-kg mudenga nekumhanya kwekutanga kwe10 m/s. Sarudza (a) simba regiravhiti pakukwirira kwepamusoro (b) kukwirira kwepamusoro.

Kukurumidza kwesimba nekuda kwegiravhiti ndeye 10 m/s²

Zvinozivikanwa:

Huremu (m) = 1 kg

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

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s²

Wanted : simba regiravhiti pakukwirira kwepamusoro uye kukwirira kwepamusoro

Solution:

(a) simba regiravhiti rinokwevera zvinhu pasi pakakwirira

Simba rekutanga remakanika:

Simba rekutanga remakanika (ME) = simba rekutanga remakanika (KE) = ½ mv_o² = ½ (1)(10)² = ½ (100) = 50 maJoules.

Simba rekupedzisira remakanika:

Simba rekupedzisira remakanika (ME) = simba regiravhiti (PE)

Nheyo yekuchengetedza simba remakanika:

Simba rekutanga remakanika = simba rekupedzisira remakanika

KE = PE

50 = PE

Simba regiravhiti rinokwanisa kukweva zvinhu i50 Joules.

(b) Kureba kwakanyanya

PE = mgh

50 = (1)(10) h

50 = maawa makumi maviri

h = 50 / 10 = mamita mashanu

Kureba kwakanyanya kwemamita mashanu kubva pasi.
