Question

find whether the accelatration is positive
negative.​

Answer 1

Answer:

The general principle for determining the acceleation is: If an object is slowing down, then its acceleration is in the opposite direction of its motion. ... Thus, this object has a positive acceleration. In Example B, the object is moving in the negative direction (i.e., has a negative velocity) and is slowing down.

Answer 2

Answer:

ok

Explanation:

if the acceleration is happening in same direction of object in which it travel then this is called a positive acceleration

but if the acceleration is happening at a opposite direction of object in which it travel then the acceleration must be negative and it is called retardation or deacceleration .
