I tried launching a pom pom with a spring a few times. The pom pom didn't launch until after
I pushed down on the spring, placed the pom
pom on it, and then let go.

The kinetic energy of the pom pom came
from potential energy in the system. How
did potential energy get stored in the
spring/pom pom system?

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

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
