What happens to the speed of a body when its kinetic energy is increased to four times the original kinetic energy?
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.
