Kushandiswa kwekuchengetedza simba remakanika pakufamba panzvimbo dzakakombama - matambudziko nemhinduro

1. Bhokisi re 1-kg rinotsvedza pasi pamusoro wakatsetseka wakakombama. Sarudza kuti simba reinetic uye kumhanya kwebhuroko panzvimbo yakaderera. Kuwedzera nekuda kwegiravhiti iri 10 m/s².

Zvinozivikanwa:

Misa (m) = 1 kg

Kuchinja kwehurefu (h) = 5 m

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s²

Kuda: Kinetic energy (KE) uye velocity zve block.

Solution:

(a) Simba reKinetic

The kwokutanga michina simba = simba regiravhiti

ME_o = PE = mgh = (1)(10)(5) = 50 Joules

Simba rekupedzisira remakanika = simba rekinetic

ME_t = KE = ½ mv_t²

Nheyo ye kuchengetedzwa kwesimba remakanika inoti simba rekutanga remakanika = simba rekupedzisira remakanika:

ME_o = INI_t

PE = KE

50 = KE

Kinetic simba (KE) = 50 Joules.

(b) Kumhanya kweBlock

Nheyo yekuchengetedza simba remakanika:

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

Simba regiravhiti (PE) = simba rekinetic (KE)

50 = ½ mv²

2(50) / m = v²

100 / 1 = v²

100 = v²

v = √100

v = 10 m/s

2. Chinhu chinorema 2 kg chinotsvedza pasi pasina kukweshana. Chii chinonzi kinetic energy uye kumhanya kwechinhu chacho pamamita maviri kubva pasi? Kukurumidza kunokonzerwa negravity i10 m/s²

Zvinozivikanwa:

Huremu (m) = 2 kg

Kuchinja kwehurefu (h) = 10 – 2 = 8 m

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s²

Wanted : kinetic energy (KE) uye velocity (v) pamamita maviri pamusoro penyika.

Solution:

(a) Simba reKinetic riri pamamita maviri kubva pasi

Simba rekutanga remakanika = simba regiravhiti

ME_o = PE = mgh = (2)(10)(8) = 160 Joules

Simba rekupedzisira remakanika = simba rekinetic

ME_t = KE = ½ mv_t²

Nheyo yekuchengetedza simba remakanika inoti simba rekutanga remakanika = simba rekupedzisira remakanika:

ME_o = INI_t

PE = KE

160 = KE

Simba reKinetic (KE) riri pamamita maviri pamusoro pevhu i160 Joules.

(b) Kumhanya kwechinhu panzvimbo yakaderera

Nheyo yekuchengetedza simba remakanika:

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

Simba regiravhiti (PE) = simba rekinetic (KE)

160 = ½ mv²

160 = ½ (2) v²

160 = v²

v = √160 = √(16)(10) = 4√10 m/s
