Question

tolong kak bantuan nya​

Answer 1

Jawaban:

D. 4

Penjelasan:

Rumus Energi Potensial:

Ep = m×g×h

Keterangan:

Ep = Energi Potensial (J atau Nm atau Kgm²/s²)

m = Massa (Kg)

g = Gravitasi (m/s²)

h = Ketinggian (m)

Ep bola 1

•h = 3m - 1m = 2m

Ep 1 = m×g×h

Ep 1 = 1Kg×10m/s²×2m

Ep 1 = 20J

Ep bola 2

•h = 3m - 2,5m = 0,5m

Ep 2 = m×g×h

Ep 2 = 2Kg×10m/s²×0,5m

Ep 2 = 10J

Ep bola 3

•h = 3m - 0,5m = 2,5m

Ep 3 = m×g×h

Ep 3 = 2Kg×10m/s²×2,5m

Ep 3 = 50J

Ep bola 4

•h = 3m - 2m = 1m

Ep 4 = m×g×h

Ep 4 = 0,5Kg×10m/s²×1m

Ep 4 = 5J

Kesimpulan:

Ep 1 = 20J

Ep 2 = 10J

Ep 3 = 50J

Ep 4 = 5J

Ep 3 > Ep 1 > Ep2 > Ep4 (D)
