Question

a sphere of mass 2 kgmoving with a velocity collides elastically with anthoer sphere which is at rest if after the collision the first sphere moves in the same direction with its velocity reduced one third of its initial velocity find the mass of the second sphere​

Answer 1

Answer:

2v +0 = $\frac{2v}{3}$ + mu

u- $\frac{v}{3}$ = v ( velocity of approach equal velocity of sepration)

u= $\frac{4v}{3}$

m=2 kg
