A runner of mass 53.0 kg runs around the edge of a horizontal turntable mounted on a vertical, frictionless axis through its cen
const2013 [10]

Answer:

0.336 rad/s

Explanation:

\omega_1 = Angular speed of the turntable = -0.2 rad/s

R = Radius of turntable = 2.9 m

I = Moment of inertia of turntable = 76\ kgm^2

M = Mass of turn table = 53 kg

v_1 = Magnitude of the runner's velocity relative to the earth  = 3.6 m/s

As the momentum in the system is conserved we have

Mv_1R+I\omega_1=(I + MR^2)\omega_2\\\Rightarrow \omega_2=\dfrac{Mv_1R+I\omega_1}{I + MR^2}\\\Rightarrow \omega_2=\dfrac{53\times 3.6-76\times 0.2}{76+53\times 2.9^2}\\\Rightarrow \omega_2=0.336\ rad/s

The angular velocity of the system if the runner comes to rest relative to the turntable which is the required answer is 0.336 rad/s

You’re traveling be same distance, but since it’s at a higher speed, you’re going faster than you were before. This meaning that it will take less time.
