A box is being pulled with a resultant force of (33i+96j)N by 3 people. Another person starts pulling the box with a force of (100i+pj)N. With all 4 people pulling the box, it moves in the direction of (12i +j). I need to work out the value of p.(adsbygoogle = window.adsbygoogle || []).push({});

For this would I add 100 and 33, and then divide by 12 to find the proportions of i. And then with that times it by the 1j to get what j is.

E.g.

100+33=133

133/12=11.1

1x11.1=11.1

96+j=11.1

j= -84.9

Or is this totally wrong?

Any help at all would be greatly appreciated. Many Thanks!
