don't remove my answer im trying my best to answer them

explanation:

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

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
