Push and Pull force

The first step is a complete success.Now there are a couple of things I cant get right in the second step.
a) I have completed all the panels(if that is what they are called) except the first one.You have renamed it yank and yeet,but I can’t remember what to actually search to find this panel.
b) The last panel that is titled “Add Impulse At Location” there are 9 subcategories. I picked the first one, but I am not completely sure if it’s the right one.
