A horizontal force of 40 newtons will just start a 600 newton empty sled moving across packed snow what is the coefficients of static and kinetic friction?
static friction= normal contact force*coefficient of static friction 40 = (600*9.8) * CSF CSF=40/(600*9.8) (you can calculate that yourself, i cant be bothered) there isn't enough info to work out the coefficient of kinetic friction
A blocks weight is 36.0 N rests on horizontal table A horizontal f. of 42 N is applied to the block coefficients of static and kinetic fric are 0.650 and 0.420 resp Will the block move under force?
In order for the block to move the force applied has to be greater than the maximum force of static friction. F > fs fs = coefficient of friction * normal force = .65 * 36N // you can use the weight for the normal force since the block is being supported = 23.4N Since applied force of 42N is greater than the 23.4N due to friction, the block will start sliding, where kinetic friction will act on the block.
How do you find force while given kinetic energy and distance?
To find force using kinetic energy and distance, you need more information. You also need the time taken to cover the distance or the speed at which the object is moving. With this additional information, you can apply the work-energy principle, which relates the work done on an object to its change in kinetic energy to calculate the force.
A 10 kg block is held in position against a vertical wall by the application of a horisontal force of magnitude 100 N as shown in the sketch The coefficients of static and kinetic friction between t?
There's no way to know, all you can say is that the upward friction force = 98,1N, and thus that the static friction coeff is bigger than 98,1/100=0,981. To know the static coeff, you should gradually make the horizontal force smaller and see when the block falls down. As for the kin. coeff, you should know the acceleration at which it is falling down.
When a force of 300 N is applied to an object that experiences 200 N of friction the net force is what?
Assuming the force of friction and the initial force oppose each other the net force is 300 N - 200 N = 100 N in the direction of the initial force.
What is the formula for the coefficient of kinetic friction?
The formula for the coefficient of kinetic friction is μk = Fk/N, where μk is the coefficient of kinetic friction, Fk is the force of kinetic friction, and N is the normal force. The coefficient of kinetic friction represents the level of resistance between two surfaces in contact while they are in motion.
What are the two kinds of friction?
There are two types of friction : static friction and kinetic friction. Static friction occurs when two objects are touching but are not moving relative to each other. For example, static friction can prevent a box from sliding down a slope. The static friction between this box and the slope (and between any objects) can be calculated using the equation : Fs = µsN where µs is the coefficient of static friction and N is the normal force. Kinetic friction occurs when two objects are touching and moving relative to each other. For example, the kinetic friction slows down a box sliding down a slope. Also, when two surfaces rub together, there is kinetic friction. The kinetic friction can be calculated using the equation: Fk= µkN where µk is the coefficient of kinetic friction and N is the normal force.

A 2.7-kg box is released on a horizontal surface with an initial speed of 2.9 ms It moves on the surface with a deceleration of 0.27 ms2 Calculate the kinetic friction force on the box?
The force of kinetic friction can be calculated using the formula: force of kinetic friction = mass * acceleration. The acceleration in this case is the deceleration, so the force of kinetic friction = 2.7 kg * 0.27 m/s^2. Therefore, the kinetic friction force on the box is 0.729 N.
What is the coefficient of kinetic energy?
The coefficient of kinetic energy is a constant for friction acting as a retarding or dissipative force to calculate the total force on the object. The coefficient of friction u is represented in equation by the relation F = u*N, where N is the normal force.
What is the coefficient of kinetic friction between a 400kg safe and the the floor when 760N are applied to the right?
The coefficient of kinetic friction can be calculated by dividing the force of friction (760 N) by the normal force between the safe and the floor. The normal force is equal to the weight of the safe, which is the product of the mass (400 kg) and the acceleration due to gravity (9.8 m/s^2). After finding the normal force, you can calculate the coefficient of kinetic friction by dividing the force of friction by the normal force.
What is the equation for sliding friction?
fk = uk*N Where fk = force of kinetic (sliding) friction uk = kinetic frictional coefficient (dependent on 2 materials sliding past each other) N = normal force (force being exerted perpendicular to the surface across which the object is sliding)
Why Kinetic Friction is constant?
Because kinetic friction is proportional to the weight of the object moving, not the speed of the object. While it definitely seems like something that moves faster should be losing more energy to friction, friction only depends on how much the two objects push against each other, not how fast they touch. Imagine what would happen if hockey players slowed down due to increasing friction as they skated faster. **Don't confuse pressure with the force of friction.** Pressure = Force/Area f = u*N (N is the normal force from the surface)
How do friction and gravity relate?
The magnitude of friction is proportional to the magnitude of the normal force which is proportional to the magnitude of gravity(The magnitude of the normal force is indirectly proportional to the magnitude of gravity.). The magnitude of the normal force, N, compared to gravity, G, on angle z, is: N=cos(z)*G On a flat surface. N=G The coefficient of friction, whether static or kinetic, f is therefore: N=cos(z)*G*f
What is acceleration if coefficient of kinetic friction is 0.15 and 730 N force is applied to 186 kg crate?
The force of friction can be calculated as 0.15 * 730 N = 109.5 N. The net force acting on the crate is 730 N - 109.5 N = 620.5 N. Using Newton's second law (F = ma), the acceleration can be calculated as 620.5 N / 186 kg = 3.34 m/s^2.
What is the value of the normal force if the coefficient of kinetic friction is 0.22 and the kinetic frictional force is 40 newtons?
The normal force can be calculated using the equation: Normal force = Weight - Kinetic frictional force. Given that the kinetic frictional force is 40 N, the normal force depends on the weight of the object and additional information is needed to calculate it.
