Question

Kinetic energy of a man is half that of a boy , whose mass is half that of the man.when the man speeds up by 5m/s then his kinetic energy is 100% more than that of boy. then find initial velocities of man and boy?
[it's a question of junior inter. pls answer in a desirable way]
hope i'll receive the answer soon.​

Answer 1

Answer:

A running man has half the kinetic

A man is running on horizontal road has half the kinetic energy of a boy of half of his mass. When the man speeds up by 1m/s then his kinetic energy becomes equal to kinetic energy of the boy, the original speed of the man is.
