Question

Two masses 2kg and 4 kg are moving with equal linear momenta. Find the ratio of their

kinetic energies.

plz answer correctly see the valuses and answer plz ​

Answer 1

Explanation:

Let the velocity be v1 and v2

K.E1=2mv2=21×v12

K.E2=2mv2=24×v22

now K.E1=K.E2

so we get v1=2v2

now ratio of momentum ratio ,n=4×v21×v1=4v22v2 

so n=21
