How Does Angling the Force Affect Kinetic Energy Increase in a Sled?

AI Thread Summary
The discussion centers on the effect of angling the pulling force on a sled's kinetic energy. When the force is directed along the +x axis, the sled's kinetic energy increases by 38 percent. The question posed is how this percentage change would differ if the force were applied at an angle of 62 degrees above the +x axis. Participants are encouraged to consider whether pulling at an angle would result in greater or lesser speed and its implications for kinetic energy. Understanding the relationship between force direction and kinetic energy is crucial for solving the problem.

Homework Statement



A sled is being pulled across a horizontal patch of snow. Friction is neglibile. The pulling force points in the same direction as the sled's displacement, which is along the +x axis. As a result, the kinetic energy of the sled increases by 38 percent. By what percent would the sled's kinetic energy have increased if the force had pointed 62 degrees above the +x azis?


Homework Equations



I'm not sure, all i have for KE is ...

KE= 1/2 mv2

Welcome to Physics Forums.

Do you have any intuition about this? Will pulling upward give a greater or lesser speed, or will it be the same?
 

Thread 'Rolling without slipping on a curved surface'

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...
