Net Force
[tex]_________________________________[/tex]
1. Boys A and B, are pulling a heavy cabinet at the same time with 5 N of force each. What is the net force acting on the cabinet?
Solution & Answer
[tex]\sf F_{net}=F_{1}+F_{2}[/tex]
[tex]\sf F_{net} = 5 \: N + 5 \: N[/tex]
[tex]\sf F_{net} = \boxed{\bold{10 \: N}}[/tex]
2. What if boy A and boy B pull the heavy cabinet at the same time in opposite directions with 10 N and 5 N of force respectively,
Answer & Solution
[tex]\sf F_{net}=F_{1}+F_{2}[/tex]
[tex]\sf F_{net} =- 10 \: N+5 \: N[/tex]
[tex]\sf F_{net}=\boxed{ \bold{-5 \: N}}[/tex]
a. what will be the net force on the cabinet? -5 N
b. will the cabinet move? Yes
c. to what direction will it move? Left
