Mr. Palmer's dog is running at you at a a speed of 3.8 m/s. She has a KE of 231.04 J. How massive is Mr. Palmer's dog? answer

32kg

Explanation:

Given parameters:

Speed of the dog  = 3.8m/s

Kinetic energy  = 231.04J

Unknown:

Mass of Mr.Plamer's dog = ?

Solution:

Kinetic energy is the energy due to the motion of a body;

Mathematically, it is represented as;

      K.E  = m v²

  m is the mass

  v is the velocity

Insert the parameters and solve;

        231.04  =  x m x 3.8²

        231.04 x 2  = 2 x    x m x 3.8²

           462.08  = 14.44m

               m  = 32kg
