Kinetic Friction Homework: F, Tension Force

In summary, an object of mass 50kg is connected by a cable to another object of mass 20kg and is being driven up an incline of 30° by a force F. The coefficient of kinetic friction between the two objects and the incline is 0.4. Two questions are asked: 1) What is the required magnitude of the applied force to move up the incline at a constant speed of 3m/s? 2) What is the tension force in the cable connecting the two objects? The user is reminded that they must show their attempt at solving the problem when posting on this forum.

Homework Statement



An object of mass m1=50kg, connected to another object of mass m2=20kg by a cable,is driven up an inclineof 30° by a force F , acting on m1 and parallel to the incline. Assuming a coefficient of kinetic of 0.4 between the two objects and the icline:

1-what should be the magnitude of the applied force to move up the icline with a constant speed of 3 m/s?
2- What is the tension force in the cable connecting the two objects?

Hi 5o5a! Welcome to PF.

You may have missed seeing in the conditions for using this forum that you must show your attempt at solving the problem when you post the question. Otherwise, it reads as though you are expecting someone to do your homework for you, and that is not the purpose of this forum.

Have you got some working to show for this problem?
 

FAQ: Kinetic Friction Homework: F, Tension Force

What is kinetic friction?

Kinetic friction is a force that acts between two surfaces in contact that are moving relative to each other. It is also known as sliding friction or dynamic friction.

How is kinetic friction calculated?

Kinetic friction is calculated using the formula F = μkN, where F is the force of kinetic friction, μk is the coefficient of kinetic friction, and N is the normal force between the two surfaces.

What factors affect the amount of kinetic friction?

The amount of kinetic friction depends on the coefficient of kinetic friction, the normal force between the two surfaces, and the roughness or texture of the surfaces.

What is the tension force?

The tension force is a force that is transmitted through a rope, string, or other flexible material when it is pulled taut by forces acting on either end. It is also known as the tensional force or the tensional stress.

How is the tension force calculated?

The tension force is calculated using the formula T = mg + ma, where T is the tension force, m is the mass of the object, g is the acceleration due to gravity, and a is the acceleration of the object.
