Two bodies have velocity in 1:2 ratio both have same weight the ratio of their kinetic energy is?

Answer»

r WEIGHT is equal then m=mass of object with VELOCITY 1xm'=mass of object with velocity 2x mg=m'gm=m'Ek=1/2 m(x)^2EK'=1/2 m(2x)^2 then you can cut same VALUES and ANSWER will come out to be 1:4
