Question

Two bodies A and B have their masses in the ratio 3:1 and K.E are in ratio 3:1,
then the ratio of their velocities are​

Answer 1

Answer:

1:1

Explanation:

Let the mass of one body be 3x and the other body be x

$KE1: KE2 = 3:1\\\frac{\frac{1}{2}m1(v1)^2}{\frac{1}{2}m2(v2)^2 }= \frac{3}{1}\\\frac{3x X(v1)^2}{xX(v2)^2} = 3\\\frac{3(v1)^2}{(v2)^2}=3 \\v1:v2 = 1: 1$
