A mass ‘m’ moves with a velocity ‘v’ and collides inelastically with another identical mass at rest. After collision the 1st mass moves with velocity 
in a direction perpendicular to the initial direction of motion. Find the speed of the 2 nd mass after collision :
A
v
B
C
v (4) 
Text Solution
Verified by ExpertsThe correct answer is:
C
before collision
after collision
In x-direction x-
mv + 0 = 0 + m υ x
⇒ υ x = υ
In y-direction y-
0 + 0 = m 
– m υ y
υ y = 
∴ Velocity of second mass after collision
υ = 
υ ’ =
