Lesson 1: Introduction to Forces

Question 101315 • [HSPHY] Physics Sem 1 (26-27)

Consider a sign suspended on a boom that is supported by a cable, as shown. What is the proper equation to use for finding the net force in the y direction?

Answer

Fnety = (FT)(sin 32°) + Fg

Fnety = (FT)(sin 32°) – Fg

Fnety = (FT)(cos 32°) + Fg

Fnety = (FT)(cos 32°) – Fg
