the resultant force is equal to all of the other forces addedView attachment 39967
someone teach me how to do these ^^^^
ALSO
someone suggest a few difficult trial papers to do for mx2 tmrw
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
