Question

the mass of a women is 4 times the mass of a girl. calculate the kinetic energy of the woman with respect to the girl if both are running with same velocity.​

Answer 1

Answer: The Kinetic energy of woman will be 4 times more than that of the girl.

Explanation:

 kinetic energy = $\frac{1}{2}$mv²

Let mass of girl be m.

    => mass of woman = 4m.

Let velocity of both be v.

K.E of girl = $\frac{1}{2}$mv²   ------ 1

K.E of woman = $\frac{1}{2}$(4m)v²  --------2

Compare K.E of woman(2) and girl(1),

$\frac{\frac{1}{2}(4m)v^{2} }{\frac{1}{2}mv^{2} }$ = $\frac{4}{1}$ = 4:1  -------  Answer
