Answer:1.084
Explanation:
Given
mass of Pendulum M=10 kg
mass of bullet m=5.5 gm
velocity of bullet u
After collision let say velocity is v
conserving momentum we get
Conserving Energy for Pendulum
Kinetic Energy=Potential Energy
here from diagram
therefore
initial velocity in terms of v
For first case
for second case
Therefore
i.e.
