in the questions involving ladders, you take moments about a point and you Do force x distance x sin/cosa
How do you know whether to use sin or cos in this situation ?
Best of luck, I've got M2 tomorrow (today) as well, and then 4 exams on Friday, and then two the following week. Help me LORD.
I have physics units 4 & 5 on Friday but not the Synoptic. I have that to enjoy next thursday. But I have an Economics synoptic instead.
Good luck with yours as well.
