Question

a body initially at rest explodes suddenly into 3 equal parts the momentum of two parts pi^ cap and 2pj^cap and their Kinetic energies are E1/E3 respectively if the momentum and kinetic energy of third part p3 and E3 respectively then the ratio E2 by E 3 is please I want answer as soon as possible


​

Answer 1

Answer:

1

Explanation:

let the mass of body  before explosion = 3m

then for momentum

2mv1 + mv2 = 0

E1 + E2 + E3 = 3mv²/2

E2 by E 3  = E2 / E 3 = 0.5 mv²/0.5mv² = 1
