Kinetic Friction Homework: F, Tension Force

AI Thread Summary
To solve the homework problem involving two connected masses on an incline, the applied force F must counteract both the gravitational component and kinetic friction. The tension in the cable also needs to be calculated based on the forces acting on both masses. Participants emphasize the importance of showing work to receive guidance, as the forum encourages learning rather than simply providing answers. The coefficient of kinetic friction is a key factor in determining both the applied force and tension. Engaging with the problem and demonstrating understanding is crucial for effective assistance.

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?
