Question

Two spheres a and b of masses m1 and m2 respectively collide

Answer 1

Different Cases arise when two spheres of Masses m1 & m2 collide.

These cases depend on their masses.

Let v1 be the velocity of the body with mass m1 &

Let v2 be the velocity of the body with mass m2 &

⇒  WHEN m1 = m2

The velocity of 1st body will become  = v2 &

The velocity of 2nd body will become= v1  

⇒ WHEN     m1 = m2   and     v2 = 0

The 1st body will stop

The velocity of 2nd body will become  = v1  

⇒   WHEN     m1 <<<<< m2    and     m2 is at rest

The velocity of 1st body will become  = - v1

The 2nd body will remain at rest.

⇒  WHEN    m1 >>>>>> m2       and       m2 is at rest

The velocity of 1st body will become  = -v1

The velocity of 2nd body v2 =  2v1
