Pojasnilo:
#a = {dv} / dt #
# => v = int a (t) dt #
# = 16 t ^ 3 + t ^ 2 + 6 t + C #
#v (0) = v_0 = -3 => C = -3 #
# => v = 16 t ^ 3 + t ^ 2 + 6 t - 3 #
#v = {ds} / dt "(v = hitrost) #
# => s = int v (t) dt #
# = 4 t ^ 4 + t ^ 3/3 + 3 t ^ 2 - 3 t + C #
#s (0) = s_0 = 1 => C = 1 #
# => s (t) = 4 t ^ 4 + t ^ 3/3 + 3 t ^ 2 - 3 t + 1 #
