i Found it tooo easy only the last part of vectors was hard

 

[Madness]

the F and T question, I found F by Wcos45 = F I dont remember the answer so is it right ?

 

[mero00060606]

i remember the final answer only it was 17 and 9.8 i remember there will be 2 equation just make the T subject then get THe F

What did you guys get for the equations of motion, that you had to form. also for the last question what did you find XY to be? (in terms of h)

 

[Madness]

Mine is wrong but I wrote like this : I found t for B then I substitute in A equation = 4.9/h

 

[coolid2012]

I got 5/3h, not sure if its correct though... what equations of motion did you get for the two particles in question 4?

T-w+f=ma
w-T = ma

the answer of the last question is 1.4h and guys tell me the answer of the 1st question

 

[Sherko]

The answers for the first question are 5u m/s and Q changing direction and impulse is 10mu Ns
The answer for the last question XY=3/2 h and the equations are for A: T-8/5g=2a and for B: 4g-T=4a

wasn't it a rough surface?!

It was a rough surface, LOL someone didnt read the question well

Yes it was a rough surface i only wrote here the final equation after simplifying see the mark scheme!!

I think you didn't get the answer right!!

where's the mark scheme?
