A thin uniform rod of mass m and length λ is free to rotate about its upper end. When it is at rest, it receives an impulse J at its lowest point, normal to its length. Then immediately after impact -
A
The angular momentum of the rod is J λ .
B
The angular velocity of the rod is 
C
The kinetic energy of the rod is 
D
The linear velocity of the midpoint of rod is 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, b, c)
Angular impulse = J λ = angular moment
Angular velocity = 
K.E. = 
Iɷ 2
and velocity of mid-point = 
ɷ
