Question

5) Two bodies of masses m and 4m are moving with
equal kinetic energy. The ratio of the velocities with
which they are travelling is​

Answer 1

Answer:

They both have equal KE then

KE1/KE2 = 1

KE1 = 1/2 mv²

KE2 = 1/4 ×4mV² = mV²

then 1/2mv²/mV² = v²/2V² = 1

v²/V² = 2

v/V = √2

hope it helpsssss

Answer 2

Answer:

as we known that kinetic energy is

1/2mv^2 =1/2mv^2

V1^2/V2^2 = 1/4
