Question
Two people push a box at the same time. A person pushes a 5 kg box with 15 N of force towards the north. Another person pushes the same box with 25 N of force towards the east. What is the net force on this box?
Answers
Fx = 25
Fy = 15
F = sqrt(625 + 225) = 29.2 Newtons
direction
tan angle above x (east) axis = Fy/Fx = 15/25
so angle above x axis = 31 degrees
compass angle = 90 - 31 = 59 degrees about northeast by east
