Solving Force of Friction for Homework

AI Thread Summary
To solve for the force of friction on a sled being pulled at a constant velocity with a horizontal force of 80 N at a 53-degree angle, it's essential to understand that the sled is not accelerating. A free body diagram is recommended to visualize the forces acting on the sled. The discussion highlights confusion around converting Newtons to grams, which is unnecessary for this problem. The key takeaway is that all forces should be measured in Newtons, and understanding the constant velocity condition is crucial for calculating friction. Proper guidance and clarification helped the participants grasp the problem better.

Homework Statement



A sled pulled out a constant velocity across a horizontal. If a is a horizontal force of 8.0 x 10^1 N is applied at an angle of 53 degrees in the ground. What is the force of friction between the sled and the snow?

Homework Equations



I convert the N into grams?
and I have to put it into uh well you know one of those sine..


The Attempt at a Solution



well first I'm so confussed with the problem... eek, can someone please guide me through it?
 
Physics news on Phys.org
Why were you thinking in converting "N into grams"?
Do you have any ideia how would you calculate the friction force?

The key word in the problem is |constant velocity|.
Draw a free body diagram, it will help, I promiss.
 
One more small tiblite of information, all forces are measured in N.
 
oooh, yeah I got it now. thanks.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
