Question

Two bodies with kinetic energies in the ratio 2:3 are moving with equal momentum . the ratio of their masses.....(A) 1:3 (B) 1:2 (C) 3:2(D)2:3​

Answer 1

Answer:

(1/2 MV²) / (1/2 mv²) = 2/3

MV² / mv² = 2/3........ (1)

Momentum of first body = MV

Momentum of second body = mv

MV = mv

V/v = m/M........... (2)

Substituting (2) in (1),

M m² / m M² = 2/3

m/M = 2/3

M/m = 3/2

Ratio of first mass to the second mass is 3:2

Pls follow.....
