Answer:
The linear acceleration of the car is 2.86m/s².
Explanation:
First of all, we have that the linear acceleration of the car and the tires is the same, because it moves ahead without disassembling itself. So, we only have to calculate the linear acceleration of the tires.
Next, it is known that the linear and angular acceleration are related by the formula:
Finally, we plug in the given values in order to calculate the acceleration:
It means that the linear acceleration of the car is 2.86m/s².
The value of the angle of the incline 
at which the block starts to slide is the angle at which the component of the weight parallel to the incline becomes equal to the frictional force that keeps the block on the incline:
where the term on the left is the component of the weight parallel to the incline, and the term on the right is the frictional force, which is the product between the coefficient of friction
and the normal reaction of the incline N.
The normal reaction of the incline, N, is equal to the component of the weight perpendicular to the incline:
Therefore, the initial equation becomes
From which we find
For angles above this value, the block will start sliding down, otherwise the block will stay on the incline.
