A particle of mass m moving with velocity 
strikes a simple pendulum of mass 
and sticks to it. The maximum height attained by the pendulum will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Initial momentum of particle = 
Final momentum of system (particle + pendulum) = 2mv
By the law of conservation of momentum
⇒ ⇒ 
⇒ ⇒ Initial velocity of system 
∴ ∴ Initial K.E. of the system 
If the system rises up to height h then P.E. = 
By the law of conservation of energy
