Answer
given,
mass of the gate = 4.5 kg
distance between the hinge 1.5 m
mass of the bird = 1.1 kg
velocity of the bird = 5 m/s
a) from conservation of angular momentum
b) There is no external torque hence, momentum is conserved
initial kinetic energy =
initial kinetic energy =
= 13.75 J
final kinetic energy
KE =
KE =
KE = 7.14 J
Kinetic energy is not conserved
hence, the collision is inelastic.
