Question

Me
two masses of 1 kg and 9 kg are moving with equal kinetic energy find the ratio of their respective linear momentum​

Answer 1

Answer:

Let the velocity of mass of 1g be x

And let the velocity of mass of 9g be y

According to question

2

x

2

=

2

9y

2

which gives x=2y

Then ratio of momentum =

9y

x

=

Answer 2

Answer:

Kinetic Energy = 1/2mv^2

= 1/2×1v^2 : 1/2×9v^2

Momentum = p^2/2m

p^2/2×1 : p^2/2×9

p^2/2 : p^2/18

= p^2/2 × 18/p^2

Thus ration = 9:1
