V(t) = ∫ a(t) dt

= 16/3 t³ + c --> saat t = 0, v = 0 (berhenti)
0 = 16/3. 0³ + c

V(t) = 16/3 t³ + 0
= 16/3 t³
a) saat t = 6 s
V₆ = 16/3. 6³
= 16/3. 6. 6. 6
= 16. 2. 6. 6

b) x(t) = ∫ v(t) dt
= 16/3 t³ dt
= 16/12 t⁴ + c
= 4/3 t⁴ + c -----> saat t = 2, x = 1
1 = 4/3. 2⁴ + c
= 4/3. 16 + c
c = 1 - 64/3
= - 61/3
x(t) = 4/3 t⁴ - 61/3
c) x = 66, 16
66,16 = 4/3 t⁴ - 61/3
66,16 + 61/3 = 4/3 t⁴
198,48+61 / 3 = 4/3 t⁴
259, 48/ 3 = 4/3 t⁴
259,48 = 4 t⁴
t⁴ = 259,48 / 4
