A steel ball o mass 
suffers one-dimensional elastic collision with a row of three steel balls, each of mass 
If mass 
has collided with velocity 
and the three balls numbered 1, 2, 3 were initially at rest, then after the collision
.png)
a)
Balls 1, 2 and 3 would start moving to the right, each with velocity 
b)
Balls 2 and 3 would start moving to the right, each with velocity 
c)
Balls 2 and 3 would start moving to the right, each with velocity 
d)
Ball 1 and ball of mass 
would remain at rest

a) |
Balls 1, 2 and 3 would start moving to the right, each with velocity |
|
b) |
Balls 2 and 3 would start moving to the right, each with velocity |
|
c) |
Balls 2 and 3 would start moving to the right, each with velocity |
|
d) |
Ball 1 and ball of mass |

(c,d) In option (a), neither momentum nor kinetic energy is conserved so collision is not elastic. Hence, option (a), is not correct b. Same difficulty lies with option (b). So, only options (c) and (d) are correct |
