Question

two balls of masses 2g and 6g are moving with kinetic energy in the ratio of3:1 what is the ratio of their linear momentum?

Answer 1

Ratio of K.E is provided so by using it we can find the ratio of velocities of both the masses which is 3:1. Now, linear momentum is Masses ×velocity hence 1:1 is the answer. I've not converted the unit of mass because in ratio it will be cancelled out.
