Diket : m = 1000 kg
           F = 3000 N
           f = 500 N
Ditanya : a
Jawab : a =  \frac{ <span>∑</span>F}{m}
            a =  \frac{3000 - 500 }{1000}
            a = 2500 / 1000
            a = 2.5 m/s2

Massa = 1000 kg
F1 = 3000 N
F2 = 500 N
ΔF = 3000 - 500 = 2500 N
F = m.a
a = F/m
= 2500/1000
=2,5 m/s²
