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 = [tex]\frac{1}{2}[/tex] m v²
m is the mass
v is the velocity
Insert the parameters and solve;
231.04 = [tex]\frac{1}{2}[/tex] x m x 3.8²
231.04 x 2 = 2 x [tex]\frac{1}{2}[/tex] x m x 3.8²
462.08 = 14.44m
m = 32kg
