Question
The minimum value of V0 such that ultimately it rolls on the upper surface. If distance AB is very large. (S is perfectly rough and V0 = 
)
- none of these
The correct answer is:
And by above
= mVR + 
Þ 
Þ 
At the time of rolling
Þ V = Rw0
By conservation of angular momentum about S during collision.
Lsi = 
Lsf = I S w1 = 
w1 = 
After collision by conservation of energy
for 
Þ 
V0 = 2Rw0 =

A uniform thin rod of mass M and length L is standing vertically along the Y–axis on a smooth horizontal surface with its lower end at origin (0, 0). A slight disturbance at t = 0 causes the lower end to slip on smooth surface along the positive X–axis and the rod starts falling. The path followed by the centre of mass of the rod during its fall is a/an.
