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 =
$frac{1}{2} times m times v{2}$
$= frac{1}{2} times 150 times 72^{2}$
$388.800$
