Question

What is the net force on this object: F norm = 20N F frict = 14N F app = 22N F grav = 20N?

Answer 1

8N i believe

Step-by-step explanation:

Answer 2

8N is the net force on the object.

Step-by-step explanation:

Given that,

`\mathrm{F}_{\text {norm }}`=20N is normal force acting upward (+20N)

`F_{\text {frict }}`=14N is frictional force which is opposite to the applied force (-14N)

`\mathrm{F}_{\mathrm{app}}=`22N is applied force which is applied on right side (+22N)

`\mathrm{F}_{\mathrm{grav}}`=20N is gravitational force acting downward (-20N)

We know that ,

`\text { Fnet }`=applied force
`\left(\mathrm{F}_{\mathrm{app}}\right)`+frictional force
`\left(F_{\text {frict }}\right)`+normal force
`\left(\mathrm{F}_{\mathrm{norm}}\right)`+gravitational force
`\left(F_{\text {grav}}\right)`

`\mathrm{F}_{\mathrm{net}}=`22+(-14)+ 20+(-20)

`\mathrm{F}_{\mathrm{net}}=`22-14+20-20

`\mathrm{F}_{\mathrm{net}}=8 \mathrm{N}`

Therefore the net force of the object be 8N.
