Question

The ratio of K.E of two bodies is 1:2 momentum are in the ratio 1:2 the ratio of mass is

Answer 1

1/2mv² = 2 x 1/2 Mv²
1/2 mv ² = Mv ²
1/2 m = M
and momentum = m x v
now first body has mass double than 2nd

so , m = 2M

therefore,
m x v = 2M x v m = 2M
mass ratio ia 1:2

Answer 2

The answer will be 1:2 Just make equations of both statenents divide them you will get v1 / v2 = 1 them put it in 1st equation one and you will get m1:m2 1:2
