Answer:
299.88 kgm²/s
499.758 kgm²/s
Explanation:
R = Radius of merry-go-round = 1.63 m
I = Moment of inertia = 196 kgm²
= Initial angular velocity = 1.53 rad/s
m = Mass of person = 73 kg
v = Velocity = 4.2 m/s
Initial angular momentum is given by

The initial angular momentum of the merry-go-round is 299.88 kgm²/s
Angular momentum is given by

The angular momentum of the person 2 meters before she jumps on the merry-go-round is 499.758 kgm²/s
There are 8 atoms okay mate
