Rotation 4 Question 1

2. Consider a body, shown in figure, consisting of two identical balls, each of mass M connected by a light rigid rod. If an impulse J=Mv is imparted to the body at one of its end, what would be its angular velocity?

(2003)

(a) v/L

(b) 2v/L

(c) v/3L

(d) v/4L

Show Answer

Answer:

Correct Answer: 2. (a)

Solution:

  1. Let ω be the angular velocity of the rod. Applying, angular impulse = change in angular momentum about centre of mass of the system

 (M) (Mv)L2=Icω=(2)ML24ωω=vL
