If body will move with double velocity after impact than after sometime it's velocity will be infinite.

How it is possible sir? After collision the velocity of body will decrease instead of increase.

@Mike!

Mathematically it's V = u but practically it is zero in my perception.

m1u1 + m2u2 = m1v1 + m2v2.

u1 = v
u2 = -v
0 = m (v1+v2)
m().

Here opposite direction. So,
v-(-v) = 2v.

They are asking combined velocity. So 2V.

Velocity after collision is zero.

BIBIN EMMANUVEL said:   8 years ago
Velocity after collision is 0.

Vinay BEL said:   5 years ago
Velocity after collision is 0.
