A rod of length l λ falls on two metal pads of same height from a height h. The coefficients of restitution of the metal pads are e 1 and e 2 (e 1 > e 2 ). The angular velocity of the rod after it recoils is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
After collision, the end A moves with a linear velocity of e 1 
. Whereas end B moves with a velocity of e 2 
.
∴ ∴ The relative velocity between the ends is
e 1 
− − e 2 
.
⇒ ⇒ The angular velocity =
