(I) A car slows down from 28 ms to rest in a distance of 88 m. What was its acceleration, assumed constant?

The  value is  

Explanation:

From the question we are told that  

       The  initial speed is   at a distance of  

        The  final speed is      at a distance of  

Generally  from the  kinematic equation we have that

=>  

=>  

=>  

The negative sign shows that it is decelerating

it has to be b, about 97 percent.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
