mass = n grams
velocity = u meter/second
Kinetic Energy = 1/2 x mass x velocity^2
K.E. = 1/2 x n x u^2
velocity = u meter/second
Kinetic Energy = 1/2 x mass x velocity^2
K.E. = 1/2 x n x u^2

This is physio's question
What will be kinetic energy of body when its mass is made four times and velocity is doubled?
