1. Bolo ea 0.2-kg, e hoketsoeng qetellong ea thapo e rapameng, e potoloha ka selikalikoe sa radius ea mithara e le 'ngoe 'me lebelo le phahameng ka ho fetisisa la bolo ke 10 rpm. Boholo ba ho potlaka ha centripetal le boholo ba matla a khatello ke bofe?

Tse tsejoang:

Boima (m) = 0.2 kg

Radius (r) = 1 m

Lebelo la Angular (ω) = 10 rev/min = 10 rev/60 s = 0.17 rev/s = (0.17)(6.28 rad)/s = 1 rad/s

Lebelo (v) = r ω = (1 m)(1 rad/s) = 1 m/s

Ho batloa: a _s le Σ F

Tharollo:

(a) Boholo ba ho potlaka ha centripetal

(b) Boholo ba matla a khatello

Σ F = ma

T = ma _s

T = (0.2 kg)(1 m/s ² )

T = 0.2 kg m/s ²

T = 0.2 N

2. Bolo ea 1-kg qetellong ea khoele e potoloha ka ho lekana selikalikoeng se bataletseng sa radius ea 1 m. Thapo e tla robeha ha khatello e ho eona e feta 100 N. Lebelo le phahameng ka ho fetisisa leo bolo e ka bang le lona ke lefe?

Tse tsejoang:

Boima (m) = 1 kg

Radius (r) = 1 mithara

Matla a tsitsipano (T) = matla a bohareng ( Σ F) = 100 N

Ho batloa: v maximum
