... A non-uniform rod AB, of mass 5 kg and length 4 m, rests with one end A on rough horizontal ground. The centre of mass of the rod is d metres from A. The rod is held in limiting equilibrium at an angle θ to the horizontal by a force P, which acts in a direction perpendicular to the rod at B, as show ...

Acceleration notes
... So, you need to think about the car’s motion when interpreting the sign of the acceleration. FYI: When a problem says “a car is moving and then it stops” its vf is 0 m/s. If a problem says that a car “starts from rest”, its vi = 0 m/s. Objects in this class will undergo something called “constant a ...
