What are super sonic speeds?

1) speeds exactly at the speed of sound

2) speeds below 343
m/s

3) speeds above 343 m/s

4) speeds at 343 m/s exactly

the answer is d. 4

hope this

also the more points you give the faster your questions get answered

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

the ima (higher than 1m) will be greater than the ima with the height of 1m.
