Terbagi 2 siklus, percepatan dan perlambatan

Percepatan
Vt = Vo + at
15 = 3 + a.6
6a = 12
a = 2 m/s2

S1 = Vot + 1/2 at^2
S1 = 3.6 + 1/2.2.6^2
S1 = 18 + 36
S1 = 54

Perlambatan
Vt = Vo + at
0 = 15 + a.5
5a = -15
a = -3 m/s2

S2 = Vot + 1/2 at^2
S2 = 15.2 - 1/2.3.2^2
S2 = 30 - 6
S2 = 24 m

Total jarak
= 54 + 24
= 78 m
