Kiyaye makamashin injiniya a saman lanƙwasa - matsaloli da mafita

1. Idan gudun ƙwallon a wurin A shine 6 m/s, gudun ƙwallon a wurin B shine √92 m/s, kuma hanzarin da aka samu saboda nauyi shine g = 10 m/s ^2. Menene tsayin wurin B (h)?

An sani:

Gudun ƙwallo a aya ta A (v_A) = 6 m/s

Gudun ƙwallon a wurin B (v _B ) = √92 m/s

Saurin gudu saboda nauyi (g) = 10 m/s ²

Tsayin A (h _A ) = mita 5.6

Cibiyar nauyi - matsaloli da mafita

1. Kayyade daidaitattun cibiyar nauyi ta abu kamar yadda aka nuna a cikin hoton da ke ƙasa.

Magani:

Raba abin zuwa sassa uku.

Yankin sashi na 1 (A ₁ ) = (2)(6) = 12 cm ²

Tsakiyar wurin yana kan axis ɗin x (x ₁ ) = 1/2 (2) = 1 cm

Ma'aunin tsakiya yana kan axis na y (y ₁ ) = 1/2 (6) = 3 cm
