A student sits in a chair that can spin without friction. The student has her hands outstretched and starts rotating at 1.9 rev/

Airida [17]

Answer:

the resulting angular speed after she pulls her hand inwards in (rad/s) is 27.02 rad/s

Explanation:

Given that :

the initial angular speed $\omega_1 = 1.9 \ \ rev/s$

Initial rotational inertia $I_1 = 12.00 \ \ kg.m^2$

Final angular speed $\omega_2 = ???$

Final rotational inertia $I_2 = 5.3 \ \ kg.m^2$

According to conservation of momentum :

Initial momentum = final momentum

$I_1 \omega_1 = I_2 \omega_2$

$\omega_2 = \frac{I_1 \omega_1}{I_2}$

$\omega_2 = \frac{12.00*1.9}{5.3}$

$\omega_2 = 4,3$ $rev/s$

To rad/s ; we have:

$1 \ rev/s = 2 \pi \ \ rad/s$

$\omega_2 = 4.3 * 2 \pi \ \ rad/s$

$\omega_2 = 27.02 \ \ rad/s$

Therefore the resulting angular speed after she pulls her hand inwards in (rad/s) = 27.02 rad/s
