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

Can kinetic energy be measured in newtons?
No, kinetic energy is measured in Joules (J), as this is the SI unit for energy.
How is the law of conseervation of energy illustrated by newtons cradle?
Newton's cradle conserves energy but converts it from potential to kinetic energy and vice versa.
When will a net force increase an object's velocity?
A net force will increase an object's velocity when the force is applied in the same direction as the object's current velocity. This will result in acceleration in that direction, causing the object's velocity to increase over time.
Suppose the force of friction on a sliding object is 25 N The force needed to maintain a constant velocity is?
100 N===========================Answer #2:That depends on the direction of the pulling force.The horizontal component of the pulling force must be 100 N.So the more steeply the rope angles upward, the harder you'dhave to pull on it in order to create a 100N horizontal component.
What does the spring scale measure if measured in newtons?
I just read that you can weigh anything on it.
What unit do you measure friction in?
you measure friction in Newtons
What is the formula for Coefficient of friction?
(Static coefficient of friction) Cf = horizontal force (newtons) required to overcome static resistance / vertical force (newtons) due to objects mass * acceleration due to gravity. Note: Moving friction coefficient is generally less.
How do you resolve a horizontal force of 40 newtons into two perpendicular directions one of them inclines by 30 degree with the horizontal and upwards?
-- The component that's inclined 30 degrees above the horizontal is[ 20 sqrt(3) ] = about 34.641 newtons. (rounded)-- The other component is inclined 60 degrees below the horizontal,and its magnitude is 20 newtons.
What is Laws of Dynamic friction?
Simplified: The coefficient of dynamic (moving) friction, is derived from: > coefficient = force resisting motion (newtons) / force of object on surface (newtons)
Can kinetic energy be measured in newtons?
No, kinetic energy is measured in Joules (J), as this is the SI unit for energy.
A horizontal force of 100 N pushes a box across a floor at a constant speed. what is the force of friction acting on the box?
If the horizontal velocity is constant, then the horizontal acceleration is zero,and the net horizontal force is zero.But if you are saying that the body was in constant motion and after that the force was applied, then the body will acccelerate because of the force. The net force applied on the body would be equal to the force applied to it when the body was in constant motion as here the force is in direction of the motion and hence the angle will be 0 giving the value of cos 0º as 1. Hence there would be no reduction in the net force
One person weighs 600 newtons and the other weighs 555 newtons Which person has more kinetic energy?
Kinetic energy measures the amount of energy a person has as they are in motion. In this instance, the person who weighs 600 Newtons has more energy.
What unit measures friction?
Friction is a force. I'll get back to that.Weight, which is usually measured in pounds or ounces or grams (depending on where you live or what you're measuring), has an official (SI) unit of newtons. An object's weight depends on the gravity affecting that object. (You probably know that you weigh less on the Moon than you do on Earth.)Gravity, which is a force, is consequently measured in newtons, just like weight. All forces are measured in newtons.Therefore, friction, which is a force, is measured in newtons.
What produces a wave potential or kinetic energy?
Either Gravity , Newtons Law , Force !
What is the metric unit for friction?
A friction is a force, so it would be measured in newtons. The coefficient of friction, on the other hand, is a ratio between two forces, so it is dimensionless.
A 26.0 KG-box was pulled horizontally in a rightward direction with an applied force of 278.0 Newtons. The coefficient of kinetic friction between the surfaces of the box and the floor is 0.230. Whats is the magnitude of the net force on the box?
2.5 m/s/s.
What are the units that friction is measured in?
The coefficient of friction is dimensionless; it has no units.
