Three forces are exerted on an object placed on a tilted
Chapter 3, Problem 43P(choose chapter or problem)
Three forces are exerted on an object placed on a tilted floor in Figure P3.43. The forces are measured in newtons (N). Assuming that forces are vectors,
a. What is the component of the net force \(\vec{F}_{\text {net }}=\vec{F}_{1}+\vec{F}_{2}+\vec{F}_{3}\) parallel to the floor?
b. What is the component of \(\vec{F}_{\text {net }}\) perpendicular to the floor?
c. What are the magnitude and direction of \(\vec{F}_{\text {net }}\)?

QUESTION:
Three forces are exerted on an object placed on a tilted floor in Figure P3.43. The forces are measured in newtons (N). Assuming that forces are vectors,
a. What is the component of the net force \(\vec{F}_{\text {net }}=\vec{F}_{1}+\vec{F}_{2}+\vec{F}_{3}\) parallel to the floor?
b. What is the component of \(\vec{F}_{\text {net }}\) perpendicular to the floor?

Step 1 of 4
a)
We are required to calculate the net force parallel to the floor.
Let us split different forces into various components as shown in the figure above.
Force \(\vec{F}_{1}\)
The force \(\vec{F}_{1}\) is itself parallel to the floor.
