Bantuin No 1 beserta cara

m= 150kg
v=72km/jam = 72000m/3600s = 20m/s
rumus =
ek=1/2 m.v²
=1/2 .150.20²
=1/2.150.400
=150.200
= 30000 Joule = 30K Joule

maaf kalau ada kesalahan dan kekeliruan

No. 1
Diketahui = M= 150 kg
V= 72 km/jam
Ditanya = Energi Kinetik=....?
Jawab = Energi Kinetik =
[tex] \frac{1}{2} \times m \times v{2} [/tex]
[tex] = \frac{1}{2} \times 150 \times 72^{2} [/tex]
[tex]388.800[/tex]
