What is the kinetic energy of a 645 n woman jogging at 0.72 m/s squared

Kinetic energy of an object is given by

here we know that

Weight of the woman is 645 N

so we will have

now we will have

also we know the speed of the woman as

so the kinetic energy of the woman is given as

so kinetic energy will be 17.1 J
