Based on human history, the likelihood that we will eventually colonize other habitable planets in our galaxy is

Going by human history, the likelihood of space colonization (that we will sooner or later colonize other planets in our galaxy that are other fit for human habitation) is HIGH. In 2005, then NASA Administrator Michael Griffin said that space colonization was the ultimate goal of current spaceflight programs.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
