Diketahui:
m=2 kg
vo=1m/s
vt=5m/s
t=2 s
Ditanya: F=....? Jika F searah
Jawab:
vt=vo+at
5=1+2a
4=2a
a=4/2 =2 m/s².
F=m.a
F=2 kg.2 m/s²
F=4 kg m/s² = 4 N.
2).Diket:
F=500 N
m=5 kg
vt=0--> berhenti
S=2 m
Ditanya:vo=....?
a=F/m
a=500/5
a=-100 m/s²-->mengalami perlambatan
vt²=vo²-2aS
0=vo²-2.100.2
0=vo²-400
400=vo²
vo=√400
vo=20 m/s.
