Answer:
C
Explanation:
Angular momentum is the product of moment of inertia and angular velocity.
L = I × ω
Since the planet follows a stable circular orbit, I and ω are constant and non-zero. Therefore, the angular momentum is constant and non-zero.
I think it’s A not 100% sure
By definition, the kinetic energy is given by:

Where,
m: mass
v: speed
Clearing the speed we have:

Substituting values:
Answer:
The jogger's velocity is:
v = 4.44 m / s
