Kushandiswa kwekuchengetedza simba remakanika pakufamba mundege yakatsamira - matambudziko nemhinduro

1. Bhokisi rinotsvedza pasi rakatsetseka risina kukweshana . Chii chinonzi kumhanya kwebhokisi kana richisvika pasi? Kumhanya kunokonzerwa negiravhiti ndeye 10 m/s ²

Zvinozivikanwa:

Kureba (h) = 8 m

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

Zvinodiwa : kumhanya (v)

Mhinduro :

Simba rekutanga remakanika (ME _o ) = simba regiravhiti (PE)

ME _o = PE = mgh = m (10)(8) = 80 m

Simba remagetsi rekupedzisira (ME _t ) = simba remagetsi (KE)

ME _t = KE = ½ mv ²

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

INI _o = INI _t

80 m = ½ mv ²

80 = ½ v ²

160 = v ²

v = √160 = √(16)(10) = 4√10 m/s

2. Chinhu chinorema 1-kg chinotsvedza pasi nemamita masere. Tsvaga simba rekufamba mushure mekunge chinhu chacho chafamba nemamita mashanu… Kukurumidza kunokonzerwa negiravhiti g = 10 m/s ²

Zvinozivikanwa:

Huremu (m) = 0.2 kg

d = mamita zana nemakumi mashanu

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

Zvinodiwa : kinetic energy (KE)

Solution:

chivi 30 ^o = h / d

0.5 = awa / 5

h = (0.5)(5) = 2.5 mamita

Kuchinja kwehurefu hwechinhu chacho mamita 2.5.

Simba rekutanga remakanika (ME _o ) = simba regiravhiti (PE)

ME _o = PE = mgh = (1)(10)(2.5) = 25 Joules

Simba rekupedzisira remakanika (ME _t ) = simba rekinetic (KE)

ME _t = KE

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

INI _o = INI _t

25 = KE

Simba reKinetic = 25 Joules.
