Question
Chapter 11, Problem 1ASA
To determine
The three general empirical rules to describe friction.
Expert Solution & Answer
Answer to Problem 1ASA
The three general empirical rules to describe friction are given below.
Explanation of Solution
Friction refers to the force resisting the relative motion between contacting material surfaces, fluid layers and material elements sliding against each other.
The three general emipirical rules for frriction includes:
- Firctional force is independent of the surface area of contact.
- Frictional force is directly propotional to the load, the perpendicular component of the force pressing the surfaces together.
- Frictional force is independent of the sliding speed.
Conclusion:
Thus, the three general empirical rules to describe friction are given above.

After the countdown at the beginning of a Mario Kart race, Bowser slams on the gas, taking off from rest. Bowser get up to a full speed of 25.5 m/s due to an acceleration of 10.4 m/s2. A)How much time does it take to reach full speed? B) How far does Bowser travel while accelerating?
The drawing in the image attached shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Side 1 has an area of 1.90 m^2, Side 2 has an area of 3.90 m^2, the electric field in magnitude is around 215 N/C. Please find the electric flux magnitude through side 1 and 2 combined if the angle (theta) made between the electric field with side 2 is 30.0 degrees. I believe side 1 is 60 degrees but could be wrong. Thank you.
