Question

Two particles of masses m and 2m respectively
have speeds v each. The ratio of their respective
kinetic energy is​

Answer 1

Answer:

1:2

Explanation:

Answer 2

Answer:

1:2

For 1st body,

Mass=m

velocity = v

KE=mv²/2

For 2nd body,

Mass=2m

velocity =v

KE=2mv²/2 =mv²

Hence KE of 1st : KE of 2nd= mv²/2 : mv²

=1:2
