IM stuck 😳.Please guide me through this question.
Right, if something is moving at constant speed, what can you say about the forces acting on it?
Resultant force is zero. If there were a resultant force there would be an acceleration according to F=ma.
So the drag force must equal to sum of the horizontal component of tension

Is this meant to be my calculation?

You got Sin and Cos wrong

And also drag force

Idk where your square root is coming from

Only take horizontal forces
No complication with mass

Also on a side note I really advise you to only highlight physics Key points.
You have highlighted words like 'icebergs' 'freshwater' which are not at all important and you have missed the most important parts 'constant speed' 'tension in two ropes are equal'
You are meant to highlight important information to make them stand out but you highlight everything including irrelevant background information that I believe it is making the question even more confusing
Just an advice

Sorry if Im frustrating you,bit I'm a bit lost.

Perhaps look at the question again, without the unnecessary highlighting, like C0balt said, highlighting words such as 'freshwater' isn't helping you. Think about what the question is asking you for, given the important information in the question.

No it's fine
Sometimes I don't bother with emote which makes my posts cold haha
No resultant force as it is constant speed.
Newton's first law states that if an object is moving it keeps moving at constant velocity until an unbalanced force is acted upon it
In other words if in constant velocity, there is no unbalanced force. Therefore all the force must equal to each other

Hey I did that calculation earlier but you said it was wrong

Thank you! 😃 .
By the way,I Assume you do international paper.Your international paper looks harder than the one we do in the UK.

Nah we do same as UK
Close enough time zone I guess
