The change in angular momentum is determined as 6 kgm²/s.
How to calculate the change in angular momentum?
The change in the angular momentum of the two objects is calculated by applying the following formula as follows;
The angular momentum of the 3 kg object;
L = mvr
where;
- m is the mass of the object
- v is the speed of the object
- r is the radius of the object
L = mvr
L = (3 kg x 3 m/s x 2 m)
L = 18 kgm²/s
The angular momentum of the 6 kg object;
L = (6 kg x 2 m/s x 1 m)
L = 12 kgm²/s
The change in angular momentum is calculated as;
ΔL = 18 kgm²/s - 12 kgm²/s
ΔL = 6 kgm²/s
