The problem involves a 20.0 kg sled being pulled across a horizontal surface at a constant velocity with a pulling force of 80.0 Newtons directed at an angle of 30 degrees above the horizontal. The objective is to determine the coefficient of kinetic friction.
There are hints provided regarding the forces acting on the sled and the relationship between friction force and normal force. Some participants are encouraged to engage more actively with the problem, indicating a mix of understanding and uncertainty among them.
Some participants have noted a lack of understanding regarding the question itself and the necessary steps to approach it. There is a reminder to utilize the homework template effectively.

Simply repeating the question isn't going to get you anywhere. If you want our help, your going to have to start doing some work.jandominic145 said:A 20.0kg sled is being pulled across a horizontal surface at a CONSTANT VELOCITY. The pulling force has a magnitude of 80.0 Newtons(N) and is directed at an angle of 30 degreesabove the horizontal. What is the coefficient of kinetic friction?
Doc Al said:Hints:
(1) What forces act on the sled? Find the vertical and horizontal components.
(2) How does the friction force relate to the normal force?
(3) What does "constant velocity" tell you about the net force on the sled?
If these questions do not ring any bells or make no sense to you, then you are not ready to attack this problem. Crack open the textbook or your class notes.
