Dik :m=2 ton = 2000 kg
t=5 s
v=20 m/s
Dit :
F=...?
Peny :
F=mv/t
F=2000.20/5
F=8000 N
∴ Gaya dorong yang bekerja pada mobil adalah sebesar 8000 N

MOMENTUMm = 2 ton = 2000 kg
Vo = 0...diam
Vt = 20 m/s
t = 5 s
F = __?
I = ∆p
F t = m (Vt - Vo)
F • 5 = 2000 • (20 - 0)
F = 2000 • 20 / 5
F = 8000 N ← jwb
catatan
F = m a = m ∆v / t
F = m Vt / t, jika Vo = 0.
