What Is the Centripetal Acceleration of a Race Car on a Circular Track?

AI Thread Summary
To calculate the centripetal acceleration of a race car on a circular track, the formula a_c = v²/r is used, where v is the velocity and r is the radius of the track. Given a diameter of 1.00 km, the radius is 0.5 km or 500 meters. The car's speed of 90.0 km/h converts to 25 m/s. Plugging these values into the formula yields a centripetal acceleration of 1.25 m/s². Understanding the relationship between centripetal acceleration, tangential velocity, and angular velocity is crucial for solving such physics problems.

HELP...new physical science student seeking to understand physics. Can you help me with this problem

A race car goes around a level, circular track with a diameer of 1.00 km at a constant speed of 90.0 km/h. What is the car's centripetal acceleration in m/s2?

Seeking to understand, or just want the solution to the problem...?:rolleyes:

Either way, please observe the forum template;
 
i need help with the formula to solve this problem. I know this is probably a super simple question but I am a struggling science student that really wants to be successful in this class. Don't just want the answer...want to understand how to solve.
 
Would it help if I told you that centripetal acceleration is somehow related to tangential and angular velocity?
 

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...
