What is the coefficient of kinetic friction between the 13.0kg wooden crate and the horizontal force of 31N of the floor?
The coefficient of kinetic friction can be calculated using the formula: coefficient of kinetic friction = force of kinetic friction / normal force. The force of kinetic friction can be found using the formula: force of kinetic friction = coefficient of kinetic friction * normal force. Given the force of 31N and normal force equal to the weight of the crate (mg), you can calculate the coefficient of kinetic friction.
How do you calculate friction equals coefficient of friction X normal force when frictional force and coefficient force are variables not given?
If both the frictional force and coefficient of friction are variable and not given, it is not possible to calculate the friction force using the equation friction = coefficient of friction x normal force. The relationship between these variables would need to be explicitly provided in order to determine the friction force.
What force is needed to slide a wooden block having a mass of 300 slugs moving across a floor if the friction is 0.80?
The force needed to slide the wooden block can be calculated using the formula: force = friction coefficient * mass * gravity. Given that the mass is 300 slugs and the friction coefficient is 0.80, the force required will be 2400 lbs.
How do you find the minimum coefficient of static friction for a mass on an incline of 32 degrees?
The equation for friction is F=uN. F (friction), u (coefficient of friction), and N (normal). So you first need to solve for the normal by using Newton's second law. Also solve for the x component of the gravity force. Since it is static friction, you know it should be at rest, so that x component force should be the same as the force of friction. Knowing that and the normal, plug it into the equation and solve for u.
How much work did the movers do horizontally pushing a 150 kg crate 10.4 m across a rough floor without acceleration if the effective coefficient of friction was 0.70?
The work done by the movers can be calculated using the work-energy principle. The work done can be found by multiplying the force of friction by the distance the crate was moved. The force of friction is the product of the coefficient of friction and the normal force (weight of the crate). The work done will be equal to the force of friction multiplied by the distance moved.

How can people influence physical weathering?
People can affect weathering physically by walking over rocks, sliding them, or anything to weather it using friction.
What are the horizontal friction coefficient calculations?
The horizontal friction coefficient can be calculated using the formula: μ = F_h / N, where μ is the friction coefficient, F_h is the horizontal friction force, and N is the normal force acting on the object. The horizontal friction force can be calculated as F_h = μ* N, where N is the normal force and μ is the friction coefficient.
Can you measure the force of friction?
Yes, the force of friction can be measured using a spring scale. The force required to overcome friction between two surfaces can be determined by measuring the force needed to move an object along those surfaces. The friction force is proportional to the normal force between the two surfaces.
What is the force of friction when a crate slides across the floor?
The force of friction when a crate slides across the floor is dependent on the coefficient of friction between the crate and the floor, as well as the normal force acting on the crate. The frictional force resists the motion of the crate and can be calculated using the equation: frictional force = coefficient of friction * normal force.
How do you find the normal force and force of friction of an object on a incline?
To find the normal force on an object on an incline, you can use the component of the object's weight perpendicular to the incline. The force of friction can be calculated using the coefficient of friction between the object and the incline, along with the normal force.
How do you calculate friction equals coefficient of friction X normal force when frictional force and coefficient force are variables not given?
If both the frictional force and coefficient of friction are variable and not given, it is not possible to calculate the friction force using the equation friction = coefficient of friction x normal force. The relationship between these variables would need to be explicitly provided in order to determine the friction force.
What is the frictional force needed to slow something down?
The frictional force needed to slow something down depends on the object's mass, speed, and the coefficient of friction between the object and the surface it is moving on. The force required can be calculated using the equation: force of friction = coefficient of friction x normal force.
If friction isn't dependent on surface area but only on the coefficient of friction between two surfaces and the reaction force then why do racing cars use bigger tires with greater area?
Friction doesnt not depend on the surface area...but the force of friction does! We cannot change the friction of a material but we can change the force due to that friction on another material in contact with it. Using this concept, racing cars have bigger tires to minimise the force of friction acting on them. They cannot change the friction of the road, so they change the resultant force on the tires.
How can you calculate friction?
Friction can be calculated using the formula: friction force = coefficient of friction * normal force. The coefficient of friction depends on the materials in contact (static or kinetic friction) and the surface conditions. The normal force is the force pushing the objects together.
How do you calculate friction?
Friction can be calculated using the formula: friction = μ * N, where μ is the coefficient of friction and N is the normal force acting on the object. The coefficient of friction depends on the types of surfaces in contact and can be found experimentally.
Horizontal force required to pull 75 kg block?
To pull a 75 kg block horizontally, you need to overcome the force of static friction between the block and the surface it's on. The force required would depend on the coefficient of static friction between the block and the surface. You can calculate it using the formula: Force of friction = coefficient of static friction × normal force.
