  1. Well let's make upwards forces have to balance downwards forces.
  2. The only downwards force we have is mg, 50 N that must be balanced by the normal force,
  3. so that has to also be 50 N.
  4. We can do the same thinking for left and right to show that this force,
  5. Brent's pushing force must equal Aayush's, so that's 100 N.
  6. Now, this problem wasn't too difficult because all of the forces where in
  7. were in what we could call the xy plane.
  8. They were all either vertical or horizontal.
  9. Let's see what happens when we make things a little more complicated.
