Solving a Constant Acceleration Problem: Help from Phil

AI Thread Summary
To solve the constant acceleration problem, start by applying the equations of motion for uniformly accelerated motion. Given the initial speed of 4 m/s and a constant acceleration of 2 m/s², calculate the time to reach point B using the formula for velocity and acceleration. Consider both tangential and centripetal acceleration components, as the motion involves circular dynamics. Identifying relevant equations, such as those for circular motion, will help in relating the concepts effectively. The solution requires a clear understanding of the relationship between linear and circular motion principles.

I got the following question:

When the car reaches point A it has a speed of 4 m/s, which is increasing at a constant rate of 2 m/s2. Determine the time required to reach point B and the magnitudes of its velocity and acceleration.


See attachment for how the diagram looks like.

Now i am not sure how to go about solving this? I have worked out the arc of the half circle but now what?

thanks
phil

concepts involved in this problem:
uniform circular motion
tangential acceleration and velocity
centripetal acceleration due to uniform circular motion
 
ya i know that, but I am stuck where i can start from?
 
perhaps the next step is to identify potentially relevant equations and see if they give you a hint as to how to relate the concepts.
 

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 '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...

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...
