Question

part 2: forces on a 100 kg trash can
move the crate off the track and into the gray box on the bottom of the screen.
place the trash can where the crate was.
make sure the boxes to display forces, sum of forces, values, masses, and speed in the green menu.
question 3
adjust the applied force on the trash can until the speed is constant at some value between 5 m/s and
a. what is the applied force? select
b. what is the friction force? select
c. what is the net force? select

Explanation:

Step1: Recall Newton's first - law

When the speed is constant, the net force $F_{net}=0$ according to Newton's first law.

Step2: Analyze the forces acting on the trash - can

The forces acting on the trash - can are the applied force $F_{applied}$ and the friction force $F_{friction}$. Since $F_{net}=F_{applied}-F_{friction}$ and $F_{net} = 0$, we have $F_{applied}=F_{friction}$.
The mass of the trash - can $m = 100$ kg, but without information about the coefficient of friction, we assume a general case for constant speed motion.

Answer:

A. The applied force is equal to the friction force.
B. The friction force is equal to the applied force.
C. The net force is 0 N.
