Verified answer
M = 2 kgv1 = 2 m/s
t = 10 s
v2 = 4 m/s
ditanya W = ...?
jawab
W = ΔEk
W = ½m(v2² - v1²)
W = ½ • 2 • (4² - 2²)
W = 1 • (16 - 4)
W = 12 J
jawaban A
Verified answer
Jawabannya:Mapel. : Fisika
Bab. : Usaha dan Energi
Pembahasan:
W = 1/2. m. (v2² - v1²)
W = 1/2. 2. (4² - 2²)
W = 2/2. (16 - 4)
W = 1. 12
W = 12 J →→ Opsi A
