V=144KM/JAM M=1500KG ENERGI KINETIK =.......?

v = 144 km/jam = 40 m/s
m = 1500 kg
Ek = 1/2.mv²
Ek = 1/2.1500.40²
Ek = 1.200.000 Joule

Ek = 1/2 mv^2

Keterangan :
Ek = Energi Kinetik (J)
m = massa (kg)
v = kecepatan (m/s)

Diketahui :
m = 1500kg
v = 144 km/jam = 40 m/s

Ek = 1/2 (1500) (40^2)
Ek = 1.200.000 J

Semoga membantu
