m = Mass of person = 65 kg
d = Diameter of round table = 6.5 m
r = Radius = 
v = Velocity of person running = 3.8 m/s
= Moment of inertia of turntable = 
Moment of inertia of the system is
As the angular momentum of the system is conserved we have
The angular velocity of the turntable is .
Answer:
Explanation:

Find x
Since the triangle is a 45-45-90 triangle, the following relationship exists
--- i.e. the other legs are equal
So, we have:
Divide both sides by 2
Take square roots of both sides
Simplify
