Three identical blocks 
and 
are placed on horizontal frictionless surface. The blocks 
and 
are at rest but 
is approaching towards 
with a speed 
.
The coefficient of restitution for all collisions is 0.5. The speed of the block 
just after collision is approximately
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
For collision between 
and 
,
Solving Eqs. (i) and (ii), we get
Hence, 
has given 
of its speed to 
and 
will also transfer its 
speed to 
.
