Answer :
Given:
The horizontal force is F = 165 N
The mass of the box is m = 7.3 kg
The box moves with a constant velocity of v = 2.9 m/s
Required:
Force of friction encountered by the box.
Explanation:
The box moves with constant velocity, so the acceleration will be zero.
The equation can be written as
[tex]\begin{gathered} F-f=ma \\ F-f=0 \\ F=f \end{gathered}[/tex]Here, f is the force of friction.
Thus, when an object moves with constant velocity, the applied horizontal force equals to the frictional force.
Hence, f = 165 N.
Final Answer: The force of friction encountered by the box is 165 N
