\There was a truck pulling a horse trailer. If the horse trailer weighted 150kg, went 250 miles, and the trucked used 20N to make this happen, what was the acceleration?

a  = 0.13m/s²

Explanation:

Given parameters:

Weight of horse trailer  = 150kg

Distance covered  = 250miles

Force applied on trailer  = 20N

Unknown:

Acceleration of trailer = ?

Solution:

According to newton's second law of motion,"the acceleration of a body is directly proportional to the force on it and inversely proportional to the mass" .

          Mathematically;

                                    F  = m x a

 where f is the force

             m is the mass

               a is the acceleration

Input the parameters and solve;

                  20  = 150 x a

                      a  = 0.13m/s²

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
