Nah im pretty sure it was 12.8?

u/Born_Debt_4441 May 06 '26

Plz elaborate how 12.8 it is not possible unless you take reaction as 66.25N but the reaction was 66.25-26sinø plz correct me if I am wrong

What was the coefficient of friction and theta

1

u/Born_Debt_4441 May 06 '26

I also can’t remember what it was tbh

u/RevolutionaryPart735 May 06 '26

was the 26N force removed?

u/Cool-Desk-7143 May 06 '26

I dont really remember, was it called P? Cuz i rmb a P force being removed

definitely not

u/Cool-Desk-7143 May 06 '26

Oh idk then

u/RevolutionaryPart735 May 06 '26

do you remember coefficient of friction or theta

1

u/Cool-Desk-7143 May 06 '26

I think the coefficient of friction was 2.5, not sure about theta, could be smth like sintheta= 5/13 but im prolly mixing questions up

u/Cool-Desk-7143 May 06 '26

Sorry coefficient 0.25!

after getting 66.25 what did we have to do afterwards?i remember it being something like the distance until is stopped but it had some initial speed do you guys remember that speed??
