Question

two bodies A and B have mass in the ratio 5: 1 and their kinetic energy are in the ratio 125:9. find the ratio of their velocities ​

Answer 1

K = mv²/2

K₁ / K₂ = m₁ v₁² / m₂ v₂²

125 / 9 = 5 v₁²/v₂²

v₁²/v₂² = 25/9

v₁/v₂ = 5/3

Answer 2

For this ratio of their velocities will be 5:3.
