Question

objects A and B of masses M and 2m are moving with same Momentum find the ratio of their kinetic energy which of the two will have larger velocity justify ​

Answer 1

Answer:

We know,

ke=p*p/2m

Explanation:

Let mass 1 be m

let mass 2 be 2m

we also know that the momentum is same, therefore p2=p2

so, ratio will be

p2/m/p2/2m

=1/2= ratio of the kinetic energies.

The object with mass m will have greater velocity as mass is inversely proportional to velocity. Lesser the mass, more the velocity and vice-versa.
