Question

Massa bus 10000 kg dan massa mobil 500 kg, maka perbandingan energi kinetik bus dan energi kinetik mobil adalah... (dik. V (bus) = 10 m/s, V (mobil) = 20 m/s)

Answer 1

Ek bus= 1/2×m bus×v bus²
= 1/2×1000×10²
=50.000 J

Ek mobil= 1/2×m mobil×v mobil²
= 1/2×500×20²
=100.000 J

Ek bus:Ek mobil=
50.000:100.000
1:2

mungkin begitu :))
