\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
