Physics: Answer a Question - Ask a Question

The aim of this thread is to revise Physics through practicing answering (and asking) questions which is one of the best ways to study. Since science is wildly enjoyable and exciting, it also goes without saying that this thread is also here for you to have a bit of fun.

The thread will essentially be a question chain where a user answers the question that has been posted above them and then asks a question in the same post for another user to answer.

Everyone is encouraged to have a go at answering and asking a question whether or not you have a degree in physics, if you are currently studying it at school, or if you are just interested in the subject broadly. If you think you know the answer, give it a crack!

To get this question chain started with something pretty simple:

Question: A ball is thrown at 15m/s at a 30 degree angle with the horizontal. It travels a horizontal distance of 12m before getting stuck in a tree. Calculate how long the ball was in flight. Show your workings.

Answer: 0.924 secs
Working is attached because I am way too slow at typing ha ha.

Question: A tractor and a trailer are connected by a rope. The tractor is towing the trailer, which has a mass of 2500kg. The tractor has a mass of 600kg. The system is accelerating at 0.4m/s.
Friction is negligible, and ignore the mass of the towing rope.
What is the tension in the rope connecting the tractor and trailer?
