Both the velocity and acceleration are vector quantities. It means that this parameter does not only have magnitude, but also the direction of motion. The direction is incorporated by the + or - sign depending on the sign convention. In this case, the downward motion is + while the upward motion is -. Thus, the velocity is equal to +0.89 m/s while the acceleration is -2.92 m/s².
Physics can demand that you start with a specific result and make general rules. Not reading the text and not solving exercises makes understanding almost impossible. It also involves a lot of math which most people do not like.

Answer:
Explanation:
Let m be the mass of a little car and m' be the mass of another car.
We know that,
Force = mass × acceleration
ATQ,
m × a = 2m × a'
a = 2 × a'
So, the acceleration of another little car is equal to .
