Question

Two bodies w of masses m and 4m are moving with equal kinetic energies. What is the ratio of their linear momenta?

(a) 1:2

(b) 1:1

(c) 4:1

(d) 1:4

I got this question during an online interview.

I want to ask this question from Forces of Nature topic in portion Gravitation of Engineering Physics I

Answer 1

Right choice is (a) 1:2

Best explanation: p = √2mE

For same kinetic energy, p1/p2 = √(m1/m2) = √(m/4m)=1:2.
