Matambudziko matatu nemhinduro nezve Momentum equation
1. Kana kumhanya kwechinhu kukawedzera kashanu kumhanya kwacho kwekutanga, saka kumhanya kwechinhu kunowedzera …….. kumhanya kwacho kwekutanga.
Anozivikanwa:
Kumhanya kwekutanga = v
Kumhanya kwekupedzisira = 5v
Huremu = 1
Zvinodiwa: Kukurumidza
Solution:
Fomura yekukurumidza
p = mv = 1 (5) = 5
Kana kumhanya kwacho kuri kashanu pane kwekutanga uye huremu hwacho huchigara huripo, saka simba racho rinowedzera kashanu pane rekutanga.
2. Chinhu chinokandwa mudenga panzvimbo yakatsetseka ine kumhanya kwekutanga kwe10 m/s. Kona yekutsvedza kwendege kuenda kune yakatwasuka i30 o . Kana g = 10 m/s 2 , saka kana huremu hwechinhu huri 2 kg, simba rechinhu mushure mesekondi imwe chete…
Anozivikanwa:
Kumhanya kwekutanga (v o ) = 10 m/s
Angle = 30 o
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Huremu (m) = 2 kg
Kudiwa: Momentum (p)
Solution:
Fomura Yekukurumidza
P = mv = (2 kg)(10 m/s) = 20 kg m/s
Kufambira mberi hakubvi pahuremu (w = mg).
3. Bara rinopfurwa nekumhanya kwe10 m/s. Kana huremu hwebara huri magiramu makumi maviri, verengai simba rebara.
Anozivikanwa:
Huremu hwemabara (m) = magiramu makumi maviri = 20/1000 kg = 0.02 kg
Kumhanya (v) = 10 m/s
Kudiwa: Momentum (p)
Solution:
Fomura yekukurumidza
p = mv = (0,02 kg)(10 m/s) = 0,2 kg m/s
