Question

In a collinear collision, a particle with an initial speed v_o strikes a stationary particle of the same mass. If the final total kinetic energy is 50% greater than the original kinetic energy, the magnitude of the relative velocity between the two particles after collision, is

(a) v₀/4

(b) √2 v₀

(c) v₀/2

(d) v₀/√2

Answer 1

Correct option (c) v₀/2
Explanation:

Momentum is conserved in all type of collisions,

Final kinetic energy is 50% more than initial kinetic energy
