So this is the question I am working on as shown in the attachment.
I got stuck in the part that I highlighted, where they divided the Dynamic temperature by 1000.
WHY ???

Any help will be appreciated,

Thank you.

It's not that the dynamic temperature is divided by 1000. (Notice: there are units attached to the 1000). You have to convert 1 kJ (= 1000 kg-m$^{2}$/s$^{2}$) into its equivalent base units so that you can calculate the rise in temperature due to the velocity of the air.
