dengan cara yaa, terimakasih
Jawaban:
Energi Kinetik (EK) = 1/2.m.v^2
m = massa (kg)
v = kecepatan (m/s)
EK = Joule (J)
1. EK = 1/2.m.v^2
= 1/2 x 4 kg x (3 m/s)^2
= 18 J
2. EK = 1/2.m.v^2
= 1/2 x 6 kg x (5 m/s)^2
= 75 J
3. EK = 1/2.m.v^2
= 1/2 x 8 kg x (6 m/s)^2
= 144 J
4. EK = 1/2.m.v^2
= 1/2 x 10 kg x (8 m/s)^2
= 320 J
5. EK = 1/2.m.v^2
= 1/2 x 12 kg x (3 m/s)^2
= 54 J
(maaf ngak nemu jawaban sesuai option a,b,c, dan d)
