Answer:
The kinetic energy of the boy is 20 times that of the kinetic energy of the girl.
Explanation:
It is given that,
The mass of the boy is 20 times that of girl.
Let and
are the mases of boy and the girls.
A boy and girl are running with the same speed.
The formula for the kinetic energy is given by :
Where m is mass and v is speed
As speed is same for both boy and girl.
Kinetic energy of a girl,
...(1)
As
Kinetic energy of a boy,
From equation (1) and (2) :
So, the kinetic energy of the boy is 20 times that of the kinetic energy of the girl. Hence, this is the required solution.
