Edexcel PHYSICS Doubts
astarmathsandphysics:
Thought it said distance is 60m but is 80
80F=750*9.8*50-1/2*750*27^2 =94125 so F=94125/80=1177N

q 22) c)ii)

What is particularly difficult about the question? They just ask you to calculate tension. Also, its not always a good idea to do questions from SAMs because they often have errors in them.

I had been thinking whether the 2 forces are going to b equal or not. So got confused. And I have seen this question not only from SAMs but from another site as well, with some other questions. Our physics teacher gave this question. Anyways, thanks for the info and help! :)
