Answer:
E1/E2 = 1/2 m1v12 /1/2m2v22 = (m1/m2) × (v1/v2)2
125/9 = (5/1) x (v1/v2)2
(v1/v2)2 = (125/9) x (1/5) = 25/9
(v1/v2) = 5/3

Answer:
✌❣✨ I HOPE HELP YOU ✨❣✌
Explanation:
Ratio of masses
m B m A = 15 and Ratio of Kinetic Energies
K B K A = 9125
Kinetic energy is K=
21 mv 2
Therefore, v B v A
= K B m AK A m B
= 9125 × 51
= 925
= 35
