Question
A bullet of mass 
is fired with a velocity of 50 
at an angle 
with the horizontal. At the highest point of its trajectory, it collides had on with a bob of massless string of length 
m and gets embedded in the bob. After the collision, the string moves to an angle of 120
. What is the angle 
The correct answer is:
Velocity of bullet at highest point of its trajectory = 50 
in horizontal direction.
As bullet of mass collides with pendulum bob of mass 3 and two stick together, their common velocity
As now under this velocity 
pendulum bob goes up to an angel 120, hence
or 
Comparing two answer of , we get
or
