Question

Benda bermasa 3kg jatuh bebas dari ketinggian 6 meter. Berapakah besar energi kinetik benda di tanah! (g = 10 m/s²

Answer 1

Verified answer

Saat benda di tanah,
Energi kinerja = energi potensial
E k = E P = m. g. h = 3 kg x 10 m/s pangkat 2 x 6 m
E k = 180 Joule.

Answer 2

Verified answer

Dik = m (massa) = 3kg
g (gravitasi) = 10 m/s2
h (ketinggian) = 6 meter
Dit = Ek (Energi Kinetik) ?
Jwb:
Ek = m × g × h
= 3 kg × 10 m/s2 × 6 meter
= (3 × 10) × 6
= 30 × 6
= 180 Joule
