someone teach me how to do these ^^^^

ALSO
someone suggest a few difficult trial papers to do for mx2 tmrw
the resultant force is equal to all of the other forces added

resultant force = 50a (F=ma)

other forces:
- gravity+normal force in the direction of resultant acceleration is 50g * sin30 = 25g (keep in mind gravity is the hypotenuse in the triangle to find this)
- F force is just F
- Resistive force is given, Rroot2 + 6v

hence, 50a = F + 25g - Rroot2 - 6v
F= 50a - 25g + Rroot2 + 6v

Oh that’s it…. You don’t wanna know what lengths I went to
So for incline plane instead of resolving horizontally and vertically we resolve perpendicular to the plane and along the plane as the y and x axis respectively?

you probably could resolve horizontally and vertically but 90% of the time it’s easier to do it in the direction of motion

Hey guys how many marks would i get for this question in part aii? idk if it should be 2 or 3 because i technically did adjust the sum..

Basically Idk how they thought of that in their solution (also why is this in q13 wtf). I tried bashing at the question and i got the required sum but also a bunch of other stuff that i couldn't get rid of so i eventually gave up on this one.
i mean surely 3 right, i coulda just done the inductive step in one line and left it but i carried it onto the next whole page
Thanks.😭
Idk I'm tired
