It means you can do 550 Newton Meters of work every second. Power is the rate of doing work, I hope this helps
A).
It would decrease because the speed of sound and temperature are proportional.
F=ma
8480=26.5m
m=8480/26.5
m=320
The mass of the cart is 320kg.
Hey,
Storage of energy is known as potential energy. If you take a spring for example, and you stretch it then you hold it, it has the energy you put into it but it is potential since it's not moving. Of course once you let go of it its potential energy turns into kinetic energy.
There are other examples as well, such as a battery. I decided to use the spring example because it is simpler.
I hope it helped.
I wrote all that^.
