Hello Aspirant,
Answer :
2
Solution :
Consider first collision
b/wb/w
Mand4MMand4M
on the right, the velocities after collision are
VM=−35u,V4M=25uVM=-35u,V4M=25u
Particle of mass
MM
will move to the left and collide with
4M4M
. The velocities after collision are
VM=(35)2u,V4M=25×35uVM=(35)2u,V4M=25×35u
So in all there are two collision.
Hope it helps!
