Coefficient of Kinetic Friction: Calculating from Homework

The applied force is constant at 43.0 N and the block has a mass of 4.30 kg. The coefficient of kinetic friction between the block and the floor can be calculated using the equation f=ma, with the acceleration being 5.3 m/s^2.

Homework Statement


A 4.30 kg block is pushed along a floor by a constant applied force that is horizontal and has a magnitude of 43.0 N. The figure gives the block's speed v versus time t as the block moves along an x axis on the floor. The scale of the figure's vertical axis is set by vs = 5.30 m/s. What is the coefficient of kinetic friction between the block and the floor?

Related to Coefficient of Kinetic Friction: Calculating from Homework

What is the coefficient of kinetic friction?

The coefficient of kinetic friction is a measure of the amount of resistance between two surfaces when they are in motion relative to each other. It is denoted by the symbol "μk" and is unitless.

How is the coefficient of kinetic friction calculated?

The coefficient of kinetic friction can be calculated by dividing the force of kinetic friction by the normal force between the two surfaces. This can be represented by the equation μk = Fk / Fn.

What factors affect the coefficient of kinetic friction?

The coefficient of kinetic friction can be affected by several factors, including the type of surfaces in contact, the roughness of the surfaces, and the presence of any lubricants or additives.

Why is the coefficient of kinetic friction important?

The coefficient of kinetic friction is important because it helps us understand and predict how objects will move and interact with each other. It is also used in engineering and design processes to ensure the safety and functionality of various systems.

What is the difference between the coefficient of kinetic friction and the coefficient of static friction?

The coefficient of kinetic friction applies to objects in motion, while the coefficient of static friction applies to objects at rest. The coefficient of kinetic friction is typically lower than the coefficient of static friction, as it takes less force to keep an object in motion than to overcome the initial static friction and set it in motion.
