Question
A set of n - identical cubical blocks lies at rest parallel to each other along aline on a smooth horizontal surface. The separation between the near surface of any two adjacent blocks is L. The block at end is given a speed v towards the next one at time t = 0. All collisions are completely inelastic, then
Options
A.The last block starts moving at t = n (n - 1) 
B.The last block starts moving at t = (n - 1) 
C.The centre of mass of the system will have a final speed 
D.The centre of mass of the system will have a final speed v.
Solution
t1 = 
(time for Ist collision)
t2 =
(time for IInd collision)
t3 =
(time for IIIrd collision)
t(n-1) =
(time for (nth) collision)
(time for Ist collision)t2 =
(time for IInd collision)t3 =
(time for IIIrd collision)t(n-1) =
(time for (nth) collision)Create a free account to view solution
