Momentum = mass x velocity
So both mass and velocity affect an object's momentum.
Answer:
The moment of inertia of the turntable about the rotation axis is 0.0225 kg.m²
Explanation:
Given;
radius of the turnable, r = 60 cm = 0.6 m
rotational kinetic energy, E = 0.25 J
angular speed of the turnable, ω = 45 rpm
The rotational kinetic energy is given as;

where;
I is the moment of inertia about the axis of rotation
ω is the angular speed in rad/s


Therefore, the moment of inertia of the turntable about the rotation axis is 0.0225 kg.m²
