F=12 N
m=2kg
vo=0 m/s
t=2 s
Ditanya V=..?
a=F/m
a=12/2
a=6 m/s²
v=vo+a×t
v=0+6×2
v=12 m/s
- Hk Newton
F = 12 N
m = 2 kg
Vo = 0
t = 2 s
Vt = __ ?
Dengan konsep Gerak dan Gaya
Percepatan
F = m a
12 = 2 a
a = 6 m/s²
Kecepatan akhir
Vt = Vo + a t
= 0 + 6 · 2
= 12 m/s ← jwb
Dengan konsep Momentum Impuls
F t = m (Vt - Vo)
12 · 2 = 2 (Vt - 0)
24 = 2 Vt
Vt = 12 m/s ←
