Q
Give the formulae for resolving the magnitudes of perpendicular vectors.
A

y = F sin(A)
2
Q
How would you find the resultant of two forces (demonstration)?
A
Set up three newton balances around a common centre point at rest.
Pull them away from each other.
Get the resultant of any two vectors, it will be equal in magnitude but opposite in direction to the third vector.
