Solving Deceleration on an Inclined Road

AI Thread Summary
To determine the deceleration of a car on a 13° uphill incline, the static friction coefficient remains constant at -4.80 m/s², which is the deceleration on a level road. The equations of motion involve the forces acting on the car, including friction, normal force, gravitational force, and any potential pushing force. The user is confused about whether a pushing force exists while the car is decelerating. Clarification on the forces involved in this scenario is needed to progress in solving the problem. Understanding these dynamics is essential for accurately calculating the new deceleration on the incline.

Quick PLEASE help :(

Homework Statement


A car can decelerate at -4.80 m/s2 without skidding when coming to rest on a level road. What would its deceleration be if the road were inclined at 13\circ uphill? Assume the same static friction coefficient.

Homework Equations


Ff=\muSFN

The Attempt at a Solution



Well I can't find anyway to even start can someone head me in the right direction?

I think I got some of it:
\SigmaF=ma
Ff+FN-Fg-Fp=ma
Ff+FN-ma-Fp=ma
+ma both sides and +Fp
Ff+FN=2ma+Fp
\musFN+FN=2ma+FpNow I'm wondering if there is actually Fp for the car or not (force of push). Would there still be a pushing force of the car when decelerating?
Stuck there now :\
 

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...
