Question

two balls each of mass M moving in opposite direction with equal speed v undergo a head on collision calculate the velocity of two balls after collision​

Answer 1

Answer:

2mv=m(u1+u2)

U1+u2=2v

Answer 2

Answer:0

Explanation:velocity is a vector quantity

So,

As per the momentum conservation formula

M(v)+M(-v)=2M(v')

0=2M(v')

0=(v')
