Question

For these last four question list the net force and direction.

Answer 1

1. 20 N right

2. 4N Up

3. 4N up

4. 2N

Answer 2

#1

$\\ \sf\longmapsto F_{net}=15+10-5=25-5=\vec{20N}$

#2

$\\ \sf\longmapsto F_{net}=12-4-4=12-8=4N\uparrow$

#3

$\\ \sf\longmapsto F_{net}=8+6-10=16-10=6N\uparrow$

They can lift the box.

#4

$\\ \sf\longmapsto F_{net}=6-4=\vec{2N}$
