Equation yesimba inoguma

Mibvunzo mitatu pamusoro peEquation yesimba rinobuda

1. Mota ine huremu hwematani mashanu inomira kubva panzvimbo yayo mumasekondi makumi mashanu, ichisvika kumhanya kwemakiromita makumi manomwe nemaviri paawa. Simba riri pamota iri…

Anozivikanwa:

Huremu (m) = matani mashanu = 5000 kg

Kumhanya kwekutanga (vo) = 0

Kumhanya kwekupedzisira (vt) = 72 km/h = 20 m/s

Nguva yepakati (t) = masekondi gumi nemashanu

Kudiwa: Simba (F)

Solution:

Verengai kumhanyisa uchishandisa fomura yeNon Uniform Linear Motion:

v _t = vo ₊ pa

20 = 0 + a (50)

20 = 50 a

a = 20 / 50 = 0,4 m/s ²

Verenga simba rinobuda uchishandisa fomura remutemo wechipiri raNewton:

ΣF = ma

F = (5000)(0,4) = 2000 Newtons

2. Mota ine huremu hwetani imwe chete, kwemasekonzi mana kumhanya kwayo kunowedzera zvakaenzana kubva pa10 m/s kusvika pa18 m/s. Sarudza hukuru hwesimba rinokurumidzisa mota.

Anozivikanwa:

Huremu hwemota (m) = 1 tani = 1000 kg

Nguva yepakati (t) = masekondi gumi nemashanu

Kumhanya kwekutanga (v _o ) = 10 m/s

Kumhanya kwekupedzisira (v _t ) = 18 m/s

Kudiwa: Simba (F)

Solution:

Verengai kumhanyisa uchishandisa fomura yeNon Uniform Linear Motion:

v _t = vo ₊ pa

18 = 10 + a (4)

18 - 10 = a (4)

8 = 4 a

a = 8 / 4 = 2 m/s ²

Verenga simba rinobuda uchishandisa fomura remutemo wechipiri raNewton:

ΣF = ma

F = (1000)(2) = 2000 Newtons

3. Maveki maviri esimba akatarisana zvichikonzera mhedzisiro ye10 N. Kana imwe yeveki dzesimba iri 6 N, sarudza hukuru hweimwe veki yesimba.

Anozivikanwa:

Simba rinobuda (F) = 10 N

Simba 1 (F ₁ ) = 6 N

Zvinodiwa: Simba 2 (F ₂ )

Solution:

F ₂ = 10 – 6 = 4 Newton
