Question

what will be a kinetic energy of a body when its mass is made four times​

Answer 1

$\huge \underbrace \mathfrak \red {Answer }$

P is proportional to the square root of kinetic energy. Since 2 and m are considered as constants. Therefore, we can say that kinetic energy increased by four times. Therefore, when the kinetic energy increases by four times, then the moment will increase by two times.

Answer 2

Answer:

hence the new kinetic energy is 16 Times to that of original
