SOLUTION TO NUMBER 7

Thank you!! So my parts i,iii and iv are correct, 2 marks lost in this question. 4-5 in question 6 means I'm in the 40s zone. Alhamdulilah, initially I thought I was in late-20s/early-30s! JazakAllah Khair Good luck with Math P3 and other exams.

I think that you have a mistake in question 6.
The answer to part one should be 17.5, as net force will be equal to 15.5 so upthrust - weight = 15.5.
Weight would not stop acting when it enters liquid.

Can you post the rest

Can you post the rest

Go through the whole thread. I've posted 2, 3, 4, 5, 6, 7.

Where does tension come into place in your equation? And I did account for the weight.

No tension, I'm talking about the deceleration when it enters water.

SOLUTION TO NUMBER 7

we had to subtract and add friction in the first part as well

 

[Oishee Asif]

Nuh-uh. When you resolve for A and B, friction's perpendicular to the direction of the tensions. It doesn't come into it.
