    Answer:

    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
