the tire of a car moving

Cars moving at constant speed on a circular race track

Explanation:

Stars and gas in the galactic disk moves in a roughly circular path about the center of the galaxy

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
