Question

1. what is the net force? a) 5.5 n right b) 5.5 n left c) 2.5 n left d) 2.5 n right 20. what symbol is typically used to draw a vector?

Explanation:

Step1: Analyze vertical forces

The vertical forces are $4.0N$ down - ward and $1.5N$ upward. The net vertical force $F_{y}=4.0 - 1.5=2.5N$ downward. There are no horizontal forces given.

A vector is typically drawn as an arrow. The arrow represents both the magnitude and direction of the vector quantity.

Answer:

$2.5N$ downward
