Question

A mass of m moves with a velocity v and collided inelastically with another identical mass . after collision the 1st mass moves with velocity vL√3 in a direction perpendicular to the intial direction of motion .find the speed of second mass after collision . [AIEEE 2005] ​

Answer 1

Explanation:

ANSWER

Particle 1 has received

l

x

=mv (in x-direction)

l

y

=

3

mv

(in y direction)

∴ Particle 2 will receive opposite impulse

⇒v

x

=

v/v

v

y=

3v

∴v= 32v
