Kushandiswa kwekuchengetedza simba remakanika pakufamba kwezviratidziro - matambudziko nemhinduro

1. Nhabvu inokandwa inobuda pasi nekona θ = 30 ^o nekumhanya kwekutanga kwe10 m/s. Huremu hwebhora = 0.1 kg. Kukurumidza kunokonzerwa negiravhiti i1 0 m/s ² . Sarudza (a) Simba regiravhiti rinogona kukweva panzvimbo yepamusoro (b) Nzvimbo yepamusoro kana kukwirira kwakanyanya

Zvinozivikanwa:

Huremu (m) = 0.1 kg

Kumhanya kwekutanga (v _o ) = 10 m/s

Angle = 30 ^o

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s ²

Solution:

(a) Simba regiravhiti

Verenga chikamu chakatarwa (v _ox ) uye chikamu chakatwasuka (v _oy ) chekukurumidza 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

Simba rekutanga remakanika (ME _o ) = simba rekinetic (KE)

ME _o = KE = ½ mv _o ² = ½ (0.1) (10) ² = ½ (0.1) (100) = ½ (10) = 5 Joules

Simba rekupedzisira remakanika

Kinetic simba panzvimbo yepamusoro:

KE = ½ mv _mombe ² = 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 rinotaridzwa rakatwasuka ne velocity yekutanga v _o = 10 m/s kubva pachivako chakareba mamita gumi. Kukurumidza kunokonzerwa negravity i10 m/s ^2. Tsvaga simba rekufamba kwebhora kana rasvika pasi.

Zvinozivikanwa:

Huremu (m) = 0.1 kg

Kumhanya kwekutanga (v _o ) = 10 m/s

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s ²

Kuchinja kwehurefu (h) = 10 – 2 = 8 m

Zvinodiwa: simba remagetsi riri pamusoro pevhu mamita maviri

Solution:

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

Simba rekutanga rekinetic (KE)= ½ mv _o ² = 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
